Sure they do. If FB stuck to legal-based censorship then they wouldn't need to ban atheist or gay rights content because those content are legal in the US. But if they swing to moral-based censorship, then those countries can appeal to morality ( their own ) and demand FB censor content in the US. Why? Because FB and tech companies have set a precedent.

What defense does FB or tech companies have against people who say they consider atheism or gay rights to be immoral or offensive? None.

What happens when criticizing a religion is considered hate speech? Wouldn't we have to ban atheism? What happens when people say they find content about gay marriage offensive?

Moral-based censorship opens the floodgates to unlimited censorship.
