I don't disagree, they definitely have the right to do the blackout, it's within the power that Reddit gave them, but Reddit also has the right to kick them out and reopen those communities, which I think is effectively going to be the same as leaving subs unmoderated. Reddit is kicking out active mods in favour of inactive ones just to open subreddits, which could turn the site into an unmoderated mess for a while... at least until more suckers sign up to do free labour for a corporation that's shown they don't give two shits about them.
