The mods are largely to blame for what is happening to that place right now. If they stuck to the spirit of the protest by boycotting Reddit while it was closed, then it would only be a little toxic.
But nope, they had to create GDTs and post on other open subs. That put their credibility and sincerity under scrutiny, and the entire blackout pointless. Nobody's buying their story that they weren't threatened - everyone's going to think that was the case and they're selfish cowards. Any attempt to now close threads for being off topic would come off as them silencing backlash.
MMA was the way to try to do it, since they actually attempted to provide an alternative site for discussion to coincide with the blackout. NBA had absolutely no credibility by not adhering to their own call for action.
I don't think that tells the full story. It really didn't seem like there was popular support there for the blackout. The threads about it beforehand, which kept getting deleted, were full of negative comments. I think people were going to criticize it regardless, and the way the mods handled it gives people another thing to make fun of.
