Any community that doesn't explicitly disallow porn ends filled with nothing but porn, so... you can see where this goes, right? OnlyFans girls: "it's free real state!"
r/linguistics is also protesting by changing the rules: 1) all posts must be links to academic articles, and 2) questions go only in the Q&A thread. That's actually worse than it looks like.
Reddit Inc.'s biggest mistake was to think that blackouts were the only form of protest, and that mods would only blackout for two days. They'll scorch the land fast.
