I like Twitter too. But I use both. Unlike your situation, I think the fediverse is a more secure place for us Chinese. On Twitter, I can't leak any of your personal info, or the police will get me. But I don't think police know about fediverse, so I can share more here. Also, Twitter has a better UI and user experience. (But I do hate Twitter's 140 char limit and randomly closing accounts.)
For fediverse, I'm on qoto. I *sometimes, but rarely* get some messages that I don't like, but it won't hurt as long as I don't care (and, I don't care since I don't like the message, what a perfect loop). For misleading and pushing-opinions-as-facts, I think they exist on both platforms, and I see more on Twitter, but less on fediverse.
(You might notice that I used a lot of "I" in my post. That's my way of emphasizing what I'm writing is my own personal view, not others' view, not fact. I won't put so much time into checking my speech is correct, so I tend to use "I think", "It might be", or "I remembered". I can think wrong, it might not be like what I said, and I can have faulty memories. That's my disclaimer, and I hope they don't annoy you. If they do, sorry about that.)
