If elon musk (or any far-right billionaire) bought Reddit, do you think there will be a mass exodus to alternatives like Lemmy, similar to the twitter exodus to Bluesky?
It depends on what changes they made. Reddit is fairly left-leaning so if they start seeing more right-wing content or racist crap being allowed on the site, it might happen.
People quit X because it allowed notorious racists and neo-Nazis back on the site, and also did dumb stuff like not allowing people to unfollow Elon Musk (it will automatically re-follow him after some time). It also prioritised and propagated right-wing content which, shockingly, left-wing users didn't like.
Anything left of Biden/Harris is met with a torrent of abuse. If anything, Reddit is split between centrists and fascists. And some of the mods will ban anyone who's active and doesn't agree with their politics.
