iirc they removed “fat people hate”, a variety of subreddits named after racial slurs (including literally /r/<n-word>s) and a subreddit for “well it’s not technically porn” of children

new Reddit remains awful both design and implementation wise but the content they cleaned up wasn’t a big loss, and there’s still plenty of “non-desirable” content (so many porn subreddits, to start) on there

That actually happened much later. I am talking about examples like r/gundeals being removed, lots of accounts asking about it then getting banned, etc. Please don't try to imply that "undesirables" means just actually offensive or illegal behavior, though there was that on reddit too. Much like what the environment of a public bar would be: informal and varied.

It is not controversial to say that the corporate environment style social rules implemented in ~2015 went far beyond gnerally offensive content to the point where it was obviously catering to whims of the advertisers demanding they not be beside content their target demographics would just not like (ie, for political reasons or whatever).
