I disagree. In this instance the ones who are angry enough to leave aren't those disaffected by the hivemind. This is happening as a result of banning and shadowbanning a lot of users. There's a lot of wack-a-mole. They've tried going hydra on subreddit creation and been shut down as soon as their posts appear on /r/al/new, they've tried invading other sites, they'll soon - in my view - turn on the circlejerk/SRD crowd having a good laugh at their expense. But ultimately they'll leave. This isn't a case of reasonable heads drifting away because of shitty behaviour, this is people leaving as a result of being banned for shitty behaviour. Normally people leave in search of better content. In this instance people are leaving looking for a platform. The difference is obvious.
You are mistaken. The angry ones are mostly staying. Have you modmail to check? A default sub to maintain? And when I check /r/all, what I see is a bunch of scrambling to quell the rebellion. There's no good way to have this discussion without it turning into a dick measuring contest so I'll simply say this: I don't see what you see and you don't see what I see.
