Censorship becomes an interesting tag, plausibly accurate, if the US Government regulates platforms further to such a degree that they make competing with them a lot more difficult, due to compliance cost & risk. That is, if the government effectively protects & entreches the existing giant platforms through regulatory action. Then these entities become something a lot closer to regulated broadcast platforms akin to radio or TV with ABC, NBC, etc. before the advent of expanded media thanks to the Internet.
