What I mean is, unlike the CCP, Congress isn't dictating what is permitted and not and what gets erased in a rather low-latency fashion. They're not telling the WaPo and Reddit and Buzzfeed to delete all posts or telling all apps and sites to remove content which makes Trump (or previously Obama) look bad... for starters and they're not controlling public opinion on social issues either as another example.

They have agendas, but they’re not dictated by the gov., although sometimes their respective agendas coincide.

It’s really not comparable.
