I consider myself a free speech absolutist. Or very nearly so. But that runs both ways. Not only do I think that almost all (to borrow a mathematical term) speech should be permitted, but also that the onus is on the speaker to make themselves heard or to find an audience. No company or platform owes them anything. In earlier times, that meant that no newspaper or printing press was required to print everything sent…
I think the interesting case is the presence of a monopolist (and I take no position here as to whether any particular company is a monopoly or not). Other [classically] liberal principles like freedom of contract have been abrogated in such cases, largely out of the realization that competition and choice are what generally make such private exercises of power acceptable.
