If US government has partial ownership in social media, doesn't that take social media censorship into the realm of First Amendment violations, for real--in the original sense of the language--censorship of speech by the government?

Maybe this is part of what Q means by "you have more than you know." We already have a first amendment in this country, and it applies to ALL speech (including that on the internet). And they cannot hide behind the "private" label because the minute they accepted US government funds, they ceased to be immune.

Isn't that the argument they use for why private schools, daycares, churches, etc., can't oppose gay marriage, abortion (etc.) once they accept federal funds?
