They operate within the law. If a government says you either ban an account in their country or you stop providing your service to the entire country, which do you think X should do? Because those are the options - follow the law or exit the country.

X are challenging the government legal orders in court btw, but in the meantime they have to cooperate. Like I said, the government are the ones censoring free speech here, not X. Do you not see the difference? To operate in a country you need to follow their laws. Not every country has free speech constitutionally guaranteed btw.
