A public forum paid for with government funds must be obligated to observe the obvious right of the sovereign people speaking there. All the FAANGs, as well as the enemedia like CNN, spend taxes forcibly taken from the people, and have no right to spend those funds to censor us contrary to the clear specification of government power in the Constitution.
Government has no rights, and no power is delegated to it lawfully to censor we rulers of ourselves. Spending funds received from government to create censored public fora is unconstitutional for very good reason.
It's not that receiving food stamps makes you publicly beholden. It's that using government funds to create a public forum does make you beholden to the rules restricting government from censoring the speech of the public. Even if those funds are attempted to be - indeed, even more importantly - covertly distributed to the fora.
