> Freedom of speech is a principle that supports the freedom of an individual or a community to articulate their opinions and ideas without fear of retaliation, censorship, or legal sanction.

Nobody is being censored by the inability of a third party to act as a parallel distribution channel. Nor does freedom of speech have anything to do with entitlement to an audience. No website infringes upon freedom of speech by having a paywall on UGC, as neither the contributors nor readers are worse off than if the site didn't exist.

Nobody is arguing about the legal boundary of Freedom of speech, you're the only one making this argument.

We're talking about the quolloquial "free speech", here.
