I think you missed the point. Nobody is shrinking or denouncing rights because right of free speech never protected against corporate sector sanctions. You are the one who is trying to expand free speech to protect you in places that no one intended.
maybe we need to re-evaluate free speech protections to bring them into alignment with today’s world, where certain corporations can be (arguably) more powerful than governments
That's arguable. Do you mean the right to free speech as found in the US Constitution doesn't extend to the corporate sector? That's true, SCOTUS agrees thus far.
Does some right to free speech not sourced in law, but perhaps morality or elsewhere, or even rooted in democracy, extend anywhere? I think that's well arguable.
