Freedom of thought and freedom to post.
Cal@kbin.social to 
Reddit Migration@kbin.social – 7 points – Reddit seems to restrict posting so much in different subs that freedom of thought is impacted. One has to think if the post is within not only Reddit rules, but the special rules in the sub, and one had to make the title and post Reddit specific in style (simple, punny, meta).
And if one happened to post a topic that was really good or great, a mod sometimes deleted the post anyway with a vague explanation.... and then you see the post appear by that same mod with slightly different wording as it was their own. Call them out on it and you were muted, and sometimes even banned.
If one had a dissenting opinion on a topic, and brought forth a compelling argument, automatically the post was downvoted by the hive-mind and no discussion took place.
They called themselves the front page of the Internet. I found the doors closed and locked and all the pens out of ink.
On Reddit, the only thing I noticed is mob mentality behavior, specially when something goes against a community's opinion. In which case, they'll try to silence you as much as possible. And never saw any subreddits with such disingenuous "policies" as the ones you commented, luckily.
Example. One of the better subreddits has a "few" rules.
The rules are too long for a post here.... so you get a small image.
Just no. Upvote and downvote is all you need.
I dunno, in most subs I'm a part of are quite okay (specifically programmerhumor, taylorswift, camphalfblood)
