I think that the John Oliver thing was useful to raise awareness, but people eventually confused a situational strategy with an actual solution.
Besides NSFW-ing, mods could’ve also promoted ad blocker usage, the sort of consumption criticism that advertisers outright despise, scorched the earth (slowly removing content from the subs), and harshly restricting the scope of the subreddit, not just through a “haha John Oliver” but a permanent solution. Or just stop moderating at all, since all those clowns that u/ModCodeOfConduct is putting on the place of older mods are incompetent clowns and powertrippers.
