wow, some of those subs are huge! After seeing what happened with Mastodon, I'd venture that Lemmy's going to see an avalanche of new users next week - look out below!
Hopefully many of these wind up staying private longer, 2 days isn't going to convince reddit admins of anything. The real shift will come when large subreddits start actively pushing their users to Lemmy or Mastodon or wherever else, nothing happens till users leave en masse.
It's likely - and is already being spoken about over at Reddit - that admins will just push out existing mods of the larger subs. I'm sure they'll find replacement mods. Or maybe just use bots.
I’d love to see this blossom into a sustained protest but I fear 2 days isn’t really going to make any difference to the situation. I also fear admins will simply assume control of protesting subreddits and remove the mods if they ever felt truly threatened. The only way to truly get your voice heard is just to leave.
