Exactly. Someone will post something abhorrent, critical replies will be removed, supportive replies will stay. It will make echo chambers worse than they ever have been. Then again, that may be exactly what the users want.

There's also the fact that nearly 100% of frontpage posts are pruned by moderators within 12 hours now. Tracked by a subreddit (RedditMinusMods) that reddit banned without reason, but you can still find a link to a graph of that happening on HN of all places: https://news.ycombinator.com/item?id=36040282
reddit ain't what it used to be.
Nobody respects etiquette anymore, and rather than upvoting valuable content they upvote whatever they like. As an extreme example, you can make the best, most honest, rational argumentation of a political issue, if the users don't agree with your stance it's going to be downvotted and hidden. Similarly, they will tolerate content that might be against the rules or the spirit of the subreddit if it's something they agree with.
On top of that, the vast majority of the time moderators enforce echo chambers themselves through bias, with a few of them going as far as banning every single user that posts in communities they disagree with, even if they have never engaged with the community they themselves moderate.
I spent a lot of time on usenet in the 1990s discussing politics there (mostly talk.politics.theory which was riven with libertarians). Given that I've lived another 40 years since then, I would simply not bother to do this anymore. Mass discussion of political issues is, in my eyes, mostly a dead end.
By contrast, locale-based subreddits, equipment-based subreddits, how-to-based subreddits remain, in my experience, relative gold mines.
You mean places like /r/korea, /r/australia, /r/melbourne etc. right?
They are the bottom of the barrel and the biggest wasted spaces due to moderator power trips and propaganda. Seriously, the moderators at these places are absolute shut-ins that subscribe to very extreme ideas and ban anything slightly away from what they believe in.
For example, Australia day is a day that celebrates Australia the country. You can be banned on Australian sub-reddits for saying "Happy Australia day" (something most Australians do). This is due to some insane, extremist ideas about Australia day.
Another example, /r/korea will silence anyone who does not agree with the US constant overwriting of Korean culture and Korean social mores. To speak on topics such as whether Korea should legalise drugs (it would be a disaster to do so, but Americans going to America) is a bannable offence.
I generally use Reddit for small topics. My home town is 80,000 people embedded in a county with a total of 150,000. Our locale-based subreddit works fine (admittedly with a lot of predictable and repeated whining from certain demographics). Our moderators are rarely in sight or even detectable.
I've written only about my specific experience. I am not too smart to be propagandized.
Big subreddits clearly have major issues, and I acknowledged that. Presumably some small ones too. The ones I tend to hang out in ... I don't see any of the issues discussed here. There are no overarching mods, there is no groupspeak (to speak of), there is little to no banning/blocking.
So sure, maybe you have experience of smaller locale based subreddit that does. That's fine, no argument from me.
Precisely and this is the misguided approach to moderation I see everywhere - it basically turbo charges cry-bullies, trolls, and people devoted to spreading misinformation.
