I would care if he did the same to Turkey or India where similar demand were made (it wasn't legislative power there, but still). I really appreciate the fact that he called Brazil out, i would have really appreciated if he called India or Turkey out, i think this is going too far.

And as for "going to far with allowing free speech", why doesn't he do the same in China, where free speech issues seems to be far greater, and the great Firewall is blocking way more than just X?

No, he was just sightly hypocritical but seemed mostly principled before this choice, now he just seems too powerful, hypocritical and egotistic. You know what my theory is? Brazil just died as a Tesla importer because of BYD, so he chose to make a stand on it, while India and Turkey used to be potential countries he could invest in at the time so he shut up and let them walk over him.

It seems its just about money, so he grandstand on his principles when almost no money is being made, and shut up when he doesn't want to upset people with dollars he could get.
