But I think the Reddit flareup is part of a more general disgust with emotionally damaged management culture which is devoted to profits before people, but is so bad at people that profits tank too.
There's a point beyond which being rich and powerful doesn't protect you from shooting off your own head. Reddit management seems to have crossed that line, and the content farm idea stops working when contributors stop feeling like they're a part of a community and realise they're really just unpaid employees on a profit production line.
So it's not just about the AMA editor. It's about the fact that management is trying to control a community it doesn't pay and doesn't really own. The "Do what you like, but give us clicks" deal has been changed to "We run this farm, we tell you what you can and can't post, but give us clicks anyway, because $business$ - oh and by the way, fuck you."
The prospects for the future are not good, IMO.
