Maybe I'm pessimistic but nothing will come from these protests. Most subs did a half-assed useless two day blackout. The subs that have gone indefinitely dark are good, but it's the users that make a difference. Reddit most likely won't see a significant drop in users or traffic.
I don't think Reddit will immediately reverse course, but I think the protest has been an absolute win simply by giving the alternative communities far more growth than they would have otherwise.
