Relying on governments to regulate mass communications is strictly better for Facebook than the alternative, where governments disagree with Facebook's chosen policies and punish them instead. This is why most companies prefer to comply with local law, only enforcing universal policy where it doesn't potentially conflict with local law.

Companies don't just have no reason to regulate language, they also have no serious authority to do so. The onus has always been and can only be on government legislators to address these issues in the most fundamental sense.

I'd like to see Facebook try to take on the Democrat/Republican eternal conflict in the US or the CCP in China on adopting a universal policy that they don't agree with, armed with powerful arguments like "the power of ethics compels me!" or "it's a Pandora's box because we're international!" or "stockholders care about our status!". Going above and beyond their most basic policy obligations has been a great way to attract the ire of political authorities who are now agitated over whether Facebook's policy is intentionally empowering or weakening their political enemies.
