You overestimate people's desire for an absolutist view of free speech. I guarantee you that if you asked people if pedos should be able to post child sexual assault material without it being taken down that the vast, vast, vast majority would say they absolutely should not be able to.

On these platforms nasty stuff always starts out as an exception but as those people realize they can stay on the platform their content increase while normal people pull the rip cord and bail out. And as the content gets reported, other platforms such as the app stores pull access to the platform making it even harder for you to reach normal people.
