I’m gonna defend meta here so hold with me for a bit.
Moderating bad actors is now impossible. They can, and do, produce so much content that any level of moderation is too expensive; even for meta. The scale of idiots to non idiots is biased heavily towards idiots. A slightly different version of “a lie can travel around the world before the truth gets their pants on”.
Meta, Twitter, google, will not save us from the bad actors. Even if they committed millions to the effort. Nor are they willing to risk litigation from the idiots in the GOP. So guess what? The only sustainable practice for them is to block.
The fact that this will prevent dissemination of legit info from the government and professionals is a problem society created by falling into the tolerance “paradox” trap.
