There's a difference between regulation and self-censoring. Major League Baseball bans a bunch of behavior that is legal from their players. Other baseball leagues could permit such behavior.
This is about both defining the regulations and practices. Other companies can have different practices. Fox News and MSNBC both report the news, but do so with very different principles and practices. But they are both beholden to the same laws (around libel, slander, etc...).
For AI these laws will be created, period. It will happen. And companies will also take on different perspectives about their own practices. As you note, there may well be laws about national security. But I imagine bland sanitization will be a feature of some versus others. The market will settle some of this, but you're short-sighted if you think the market will be the arbiter of it all.
