Right to Privacy is the first thing to come to mind. It's worse in that this is not the federal or state government collecting data, it's a private enterprise. After that, there are frankly glaring Freedom of Speech infringements here, as the definition of obscene content is hand-waved. You can talk academically about making crystal meth on YouTube, but somehow specific content is restricted, not due to the protection of civilians, but due to individual tastes.

None of this falls under the purview of the government of the United States. I'm betting it's a rather damaging election year shenanigan.
