I mean, well, an absolutist free speech ethos. That there should be no interference with free speech at all by anyone ever.

I don't have draft legislation on this point, in no small part because most of this has nothing to do with government restrictions. More to do with how people get all weird when someone like youtube decides to not give a platform to people that use the platform in part to directly cause harm to innocent people. That sort of thing.
