I’m very suspicious of Meta and its intentions. I also don’t think I’m better than a Meta user except in my choice of social media platforms, which is only even possible because I haven’t gotten myself into social groups that primarily communicate there. Not everyone is so lucky. If my social group were slightly different I might be a resentful Meta user holding my nose because I would value having a social life over avoiding a company that’s got pretty much everyone entangled anyways. I’d probably try to get people to move platforms, and probably complain about Facebook and Meta as often as I could without annoying everyone, but it’s very likely that they wouldn’t all move off the platform just because one person in the group hates it.
Meta users are welcome to come here. I want everyone to have a non-enshittified, non-corporate social media and that includes people who are currently on an enshittified corporate social media. But Meta itself is not welcome. That means no Threads, no touching us with Meta, go make a non-Meta Fediverse account first. Even if defederating them might not be the most effective, even though they can scrape all our stuff regardless of their federation status, I want to send the message that Meta is very unwelcome here. But its users are welcome. We shouldn’t try to hoard the non-enshittified place all to ourselves. Only gatekeep the place from people who will try to enshittify it—and Grandma from Facebook is not going to try to squeeze us for cash.
