Yeah I fully expect reddit to replace the moderators but it will take time and effort to select the right people.
If all the mods who protested actually resigned or moved their subs to being unmoderated it would've crippled the site, reddit would not be able to replace them quick enough.
It's unfortunate that the threat alone was enough to get most of them to reopen.
Reddit threatens the mods of r/CyberpunkGame (the main subreddit for Cyberpunk 2077). Mods decide to go down in a blaze of glory, whole sub agrees. (old.reddit.com)
Surprising nobody, Reddit Corp threatening a gaming sub of a fanatically anti-corporate video game doesn't go as they'd hoped....
r/TIHI has been banned for being unmoderated. (old.reddit.com)
