Sadly there’s always going to be people that will do this just for the feeling of insignificant power they get from moderating a subreddit
I don’t see myself going back to Reddit if they keep those subs closed down. However I do believe that if this “strike” goes on for longer than a week or so, the admins will forcefully replace each closed subreddit mods to make them live again.
I guess they did not rock and did not stone quite enough
