That's not the same point. Again, I have no problem believing that what you say happens, even often. Even still, some topics may really be censored. They may even be the same topics; just because there's an angry mob on one side of a topic doesn't mean that everyone on that side of the topic is wrong, and that's the hardest situation to moderate dispassionately. Maybe even impossible. Which is when I can imagine platforms getting frustrated and resorting to topic censorship.
