I was just talking to a friend who's very anti-nazi (at least, that's what he says), told him that by staying there, he's feeding the nazis. He says that he's the resistance working from within lol. People would tell themselves all kinds of stories for convenience.
I mean, there's no comparison. Punching Nazis is always cool, Twitter is just talking to them, which never is. You and fifty friends go on Twitter and dunk on Nazis all day and you're still just at a table talking with the enemy. Take fifty friends to a Nazi bar and throw punches, you've just improved the neighbourhood.
Most of them have gone to BlueSky. A few are on Mastodon but rarely as their primary (sadly). A lot of artists have gone to places like FurAffinity, Pixiv, and to a lesser extent DeviantArt.
Unfortunately a lot of them have just resorted to being on Patreon, which is unfortunate.
I actually emailed my local National Weather Service station awhile back asking if they’d post on Mastodon and even offered them a BlueSky invite and they wrote back saying only Twitter and Facebook were allowed and they’d be everywhere if it was approved by higher ups.
Someone made a BlueSky bot a few months ago for NWS notices and I’m pretty sure they covered every local one. I remember the person who made it asking people to request any missing stations. Not sure if there’s a Mastodon equivalent but you could use a bridge. It won’t help with transit delays or other local government announcements but the weather service stuff is available (via an AtProto <-> ActivityPub bridge if nothing else; it’s not like you interact with the posts so it’d be ideal for a bridge).
