The thing that saddens me the most about the whole fedi/meta drama is a thing I can't prove, but that I think is likely because I've worked in these kinds of tech companies.
The notion that Meta is looking to embrace/extend/extinguish the fediverse is laughable. The entire fedi userbase is a rounding error for Meta. They arent looking to take down the fediverse, they're trying to take down TWITTER.
They want the celebs and journalists back. Take advantage of Twitter's tarnished reputation.
