The article points to an ongoing conference as the source, unfortunately (despite having no registration fee) the live-stream is password protected for non-participants :(
Edit: It seems the talks may be released, in the end

But, although I've never run a conference, I naively can't see that broadcasting the plenary session's video a little broader (to the three to five latecomers likely to stick around!) would really cause problems.
Not to be a stereotypical "Concerned Facebook Taxpayer", but in general I'm really fond of CERN's transparency, and I appreciate all the work they do to keep science open.
They're usually way ahead of the field and it's refreshing to see, I love following what comes out of the LHC data.
So all that to say, maybe I've set my expectations a little high when it comes to physics and public access =)
Many online conferences I've attended this past year have both a Zoom meeting for registered participants and a YouTube "simulcast" for people who don't care about asking questions. I haven't run one and don't know if the logistics are complicated; maybe the organizers just didn't think of doing it. Anyway, these days most conferences seem to be pretty quick at putting videos out, though of course our attention will be elsewhere next week...
