What happens if people start talking about how much they hate Zuckerberg and start looking for alternatives and the cool kids start suggesting each other some other social network that's technically good enough but never took off because didn't benefit from the network effect?
Then anything he touches becomes toxic. Zuckerberg isn't even divisive like Trump, he may have issue finding people to rally with him against the deserters.
Please, no, not yet another open and federated social media platform that is in fact not much more than an endless feed of bots posting and reposting twitter posts and rss feeds. The internet can't take much more of those.
I wanted these platforms to succeed, I've had an account and tried using most of them - Diaspora, Friendica, Red Matrix, someothermatrixIdontrememberthenameof, Mastodon, identica/statusnet, ... They're all the same. (I'm sure I'm forgetting at least one or two, but they all blend together.)
