A lot of people are making false assumptions that Elon isn't fighting for free speech in China that couldn't be more false. X is banned in China. He uses his popularity there and Teslas strong presence in China as leverage to push the issue behind closed doors. With the Chinese leadership if they feel they are being pressured publicly they double down. Elon is very popular in China and you can bet he uses that to fight for what he believe in more than anything.
