I mean, that is a thing apps could have done to resolve the situation, the fact they chose not to take that route wasn’t Reddit’s decision. (Not that I blame devs for not wanting to play ball after seeing how Reddit’s team slandered the Apollo dev, that was inexcusable and likely burned a lot of bridges.)
r/gaming has mentioned receiving similar threats, so it might be that more are getting them but by and large only the “edgier” (not meant derogatorily, just can’t think of a better term for it) subreddits going public about it?
