To be honest, I don't think the forced political content on Reddit is going to decline in any meaningful way going forward. I think the people who are constantly pushing the political content realize how powerful of a reach they have and there's no reason to slow down. You're already seeing new subreddits like "MurderedByAOC", despite the fact that AOC tweets always get posted to every major subreddit.
There's no way murderedbyAOC isn't run by her staff. It only costs about $50 to buy enough upvotes to get on the frontpage of reddit (less once people start subscribing and upvoting organically), that's probably some of the cheapest advertising-per-eyeball you can get.
