This pretty much sums up my experience too. It's been downhill since all the subreddit bans a couple years ago. I miss r/consumeproduct.
Out of the list on Wikipedia [1], the utter majority of banned popular subreddits were far-right, terrorist, violence-oriented or dealt with questionably or outright illegal sexual material (jailbait, fappening).
As for r/consumeproduct, there's a Google doc floating around detailing its links to the far-right and transphobes [2]. Doesn't sound surprising to me that they got banned.
