I guess filtering is level of: "My 11-year-old son keeps talking about this Linux thing with his computer. What is Linux? Is it a hacking tool? Should I be worried?"

Probably entirely unrelated to the distrowatch thing.

Who knows? The article says "I've tried to appeal the ban and was told the next day that Linux-related material is staying on the cybersecurity filter." -- presumably we could ask Distrowatch to share the exact wording of the response they got back, but the fact FB apparently responded in such a way suggests it wasn't a filter specific to Distrowatch.

I think the Distrowatch author is just missummarizing the interaction. https://news.ycombinator.com/item?id=42848244

Maybe! We're all just speculating about the degree of accuracy here. I messaged them on Mastodon to see if they will clarify the text. Will post back if I hear from them.

This is Facebook, where people regularly post something in group A and think they posted it in group B, and then complain that their post was "deleted" or "censored".
