I don't know why you'd switch from the clusterfuck that is Twitter to anything made by Meta, one of the worst tech companies out there. It's like trading a turd for a piece of shit.
Mastodon is the only reasonable alternative IMO, the only problem is that not enough people are on there.
well, that's going to change as soon as Threads will be available for federation. Then you can use Mastodon and be in direct contact with all the folks from the Meta-verse.
