IMO the reason why BS just ended up being Twitter 2.0, or 1.2 even, or why Twitter went down its path in the first place, is that the US and EU are no longer producing enough content to justify ownership or continuous iterations of such a system.

Otherwise it wouldn't have been forced upon who begrudgingly got funding secured. Any of then-GAFA could have bought it and none wanted to touch it.

The bad moderation on those platforms, I think, is a desperate attempt to align platform cultures to the moderating entities' standards that are no longer comprehensible to users, if known at all, like a kid on a push car moving away from the park trying to steer it back.

It seemed fine until 2015 or so, streaming hundreds of novel tweets per second per user, many with novel images. Then things went downhill. Musk can't be the sole villain in it.
