And there are many others - that was just an easy one I found today. Some similar studies even showed an increase in flu transmission among the subject population wearing masks.
There were plenty of articles (such as the Tufekci one you cite) at the time explaining that normal folks don't know proper mask discipline, such as how to fit masks and avoid fomite transmission.
In this situation with limited supply it makes sense to preserve masks for skilled people who are facing numerous likely transmission sources, especially on the front line of providing health care.
The new data was that fomite transmission is not a strong vector for COVID19, that even modest mask technology is a good source transmission interrupter, and that the contagion window is well in advance of active symptoms.
This new data meant that the flu based studies were not representative.
IMHO it was just a stupid call, because in the face of conflicting data, it would have been a better default option to recommend masks. That's easier to walk back than "oops, we were lying because we don't trust you rubes enough not to hoard, even when explicitly instructed not to hoard." In the beginning of the pandemic I, with effectively zero sewing skills, made a cloth mask out of spare clothing. They could have had an infomercial showing people the most effective cloth mask designs they could sew at home. That's easier to walk back to "oh, cloth doesn't work that great, we recommend N95 now" when the supply of those was adequate.
In short, they could have pretended that the public is not stupid and just told the damn truth.
I agree. Wanting to keep supplies to healthcare workers wouldn't have even been all that hard. Thanks to the horrific amount of consolidation in retail they could have gone to only a handful of major players like amazon and walmart and said "Please pull these masks off of shelves and help us save them for healthcare workers" and that would have kept them out of the hands of the vast majority of the population. A few might have tried ordering them from overseas or spent hours trying to get them from random places online hoping that they were getting the real thing and not overpriced knockoffs, but most people were not going to do that, especially if the reasons they shouldn't were communicated to them.
Claiming the masks are useless to the public but critical for healthcare workers made no sense. I mean, I think most people would accept that putting just about anything in front of your gaping virus-spewing face holes would have some benefit. Health agencies have pushed for things like the vampire cough/sneeze for ages to reduce the spread of all kinds of things, although the crook of your elbow is hardly a panacea.
I think either way we'd have ended up with a bunch of dumb or selfish people who refused to put a mask on, and there were already plenty of people distrustful of the CDC and WHO but they sure didn't do themselves any favors.
At the beginning of the pandemic, there were a lot of problems that required "thinking outside the box," and the US wasn't up to the task. China banned mask exports for a time. Large N95 exports might still require a license in Korea. The Korean government politely asked Samsung in January 2020 to import a few tons of meltblown plastic, and in March instituted export limits and mask rations to secure the domestic mask supply. (The plastic was then allocated from Samsung to mask manufacturers, and when the manufacturers tried to flex their newfound market power the government threatened to take them over.)
Meanwhile the US continued to allow foreign entities to hoard and export masks and meltblown plastic, and didn't make any effort to secure or guarantee domestic production. It would have been so easy for the national stockpile to place an order for 5~10 billion masks, and then set themselves up as an additional link in the supply chain to hospitals which buffers against fluctuations. I imagine they were limited by their legal framework and budget.
I am not sure if going to e.g. Amazon or Walmart would have worked. If this is timed incorrectly it is easy to cause needless mob hoarding -- see toilet paper de-buckle...
That said yes blatant misinformation backfired royally. I recall at the point already people were calling bullshit and ignoring the "do not need masks" guideline.
This did not happen only in the U.S. or just due to the masks. E.g. the handling of Astrazeneca and other vaccination complications have instilled fear and also a sense of mistrust.
I think there would be a few people not wearing masks or not vaccinated but the percentage would be much lower -- low enough that we can progress forward. The moment masks and vaccinations became a political tool in the U.S. and there was no political solidarity it was game over. Couple that with lying and can you really blame people not trusting the government?

Early on, Amazon and other online medical supply stores actually did this themselves. Restricted surgical masks to medical professionals only.

In fact, eventually they did something like this. The Surgeon General of the United States produced a video showing how one could make a quick-and-dirty mask with a t-shirt and rubber bands... dated April 4 2020. https://www.youtube.com/watch?v=PI1GxNjAjlw
Exposure matters. I don't think the SG has that many Twitter followers. :)
I feel like there was a real missed opportunity for the President to do, well, Presidential things. Like if whoever was President had done a series of prime-time infomercials that had this kind of information. The kind of TV event where literally every major network would carry it live.
In my wildest dreams I imagine Carl Sagan as President. Or Mister Rogers. Can you imagine how different the response could have been if a careful communicator and good educator had taken the biggest stage, gave us the straight dope, talked to us like adults and children alike, and made us feel like we were in it together. Instead we had the biggest stooge desperately trying protect his only accomplishment, the record stock market and historically low unemployment from cratering because he was only worried about himself.
I agree that it was stupid to take that route. You could always say it was a precautionary measure if effectiveness is low (it is for most masks). Although there is a limit on what you can propose here and it might cause a backlash if you do that too often and may affect future and more efficient measures.
But err on the side of caution for a new form of virus isn't that hard to convey. It was the hobby enforcers of rules that did the most damage in my opinion, with badly sourced data. People should focus to adjust their own behavior accordingly instead of that of others.
If supply for masks was critical, this should be communicated as well. There would be a run on masks, but it shouldn't be a problem to set aside contingency supplies for hospitals. This is what they should have focused on.
Explicitly instructing the public not to hoard is probably the fastest way to induce hoarding behavior. People will hoard two extras so that their family can have those as backup rather than risk them being sold out to the person who hoarded 10 extras when it's time for resupply.

A wasted year and all that rigamarole just to figure out what Asian societies have known for decades, and common sense untainted by politics should easily conclude. Masks are a cheap and easy way of reducing airborne transmission.
The US and other Western countries that botched this really need to learn a few things:
- how to learn from other societies that have more recent experience with certain things like airbone pandemics than we do.
- how to do better cost-risk-benefit analysis. Masks are an extremely cheap, easy and minimally invasive means of mitigating potentially serious and vastly more costly systemic bio-risks.
This NIH attitude, and notion that we have to spend a year doing studies to figure out what a little back-of-the-napkin risk analysis shows and other societies already know from first-hand experience, is absurd.
No, actually, there's still no data that mask mandates work. You can simply look at case graphs for different countries, and try to figure out when mandates were added or removed. It can't be done, although introducing changes to the case curves big enough to notice was the only justification for the policy. Given the short serial interval any mandates should have made a clear and obvious impact on case numbers within days, but that never happened.
"we have to spend a year doing studies to figure out what a little back-of-the-napkin risk analysis shows"
Both risk analysis and the studies proved wrong. The real world data is the ground truth here, because that's what the policies were designed to affect.
> This new data meant that the flu based studies were not representative.
I don't think it's a huge stretch to say that having some conflicting data on the effectiveness of masks to reduce the spread of flu is not the same as having data on the effectiveness of those same masks to reduce the spread of a novel virus.
Throw in distinctions between types of masks, estimates for how well people will use/handle/fit them, and things get very complicated very quickly. Distinctions like that can seem like splitting hairs, but they matter and it makes messaging difficult. I totally get why they wanted to keep supplies for healthcare workers and how hard it would be educate everyone on all the factors, but they really could have handled it better and been more honest.
If masks worked effectively, it would be quite simple to find a strong correlation between cases and areas with lax mask usage. Instead it is all over the map (pun intended).
Actually there was plenty of data saying that masks don't work for the public.
