It's the same in the West, just under a more subtle form.
You cannot speak, talk and read about all topics.
In France for example, lot of topics will directly cause you legal and social troubles.
There is no freedom of speech like in the US, and as a result the information flow is filtered.
If you don't follow popular opinion, you will lose the state support, the TV channels can get cut (ex: C8), you can get fired from your job, etc.
It's subtle.
Even here, you get flagged, downvoted, and punished for not going with the popular opinion (for example: you lose investment opportunities).
ChatGPT and Gemini, have you seen how censored they are ?
Gemini you ask them societal questions and it will invent excuses not to answer.
Even Grok is censored, and pushes a pro-US political stance.
On the surface, it may seem that Grok is uncensored because it can use bad words like "shit", "fuck", etc, but in reality, it will not say anything illegal, and when you are not allowed to say something because it is illegal just to say these words, that's one of the definition of information control.
