Is It Possible to Find State Action in the Guse of a Private Company?

The argument is really simple. If the government can't do something under the constitution, then the government cannot deputize a private company tog do that same thing. A case called brentwood lays out the standards for finding state action in the guise of a private enterprise. And farthing about what we see with modern big tech censorship todays. They're the white house boasting every day, every week nowadays, about working with social meda companies to remove misinformation or hate speech. So couldn't you extend that argument to industries beyond silicon valley? I think some of the same principles could absolutely apply.
