Officially yes. I got banned for saying "Musk fuming is violently toxic", site wide and permanently from 6 subreddits. Others got banned just saying "Luigi is innocent". Try it out. That reads more like quashing free speech to me.
Disinformation in the ads, yes. Also front page stuff making past moderation. Today in r/science I saw "Democrats are less tolerant of Republicans than vice versa" and a load of unscientific hogwash saying Republicans are not as intolerant as Democrats think. Go find it yourself if you don't believe me.
That seems like a platform of disinformation to me.
I mean, usually people don't say "I am disinforming you, hah!". We can only rely on that weird feeling that something isn't right. That's what makes it so pernicious compared to plain good faith misinformation.
