This is how "independent media" work in most countries that have such a thing: different outlets are controlled by different people, resulting in some diversity of opinion, but not every idea gets the same airtime. Of course the definition of "going wild" is different in a Chinese context.

Also, from the article you linked:

> 04/13/2020 UPDATE RSF has taken note of the video published on the Weibo account of the whistleblower Ai Fen, which suggests that she is free to move, and hopes that it was not staged by the Chinese regime.

That depends on what you mean by "freedom of anything". Are people allowed to do everything they want to? No. Are they doing it anyway? Yes.

More concretely with regards to freedom of speech: Are independent media allowed? No. Do they exist anyway? Yes.

> Their government is attempting to govern their lives with a mandatory government issued social media account.

What? That part makes me wonder whether all my knowledge is outdated because I haven't been to China this year and nobody told me about this or whether it's you who's been away for too long.
