IME most people calling themselves a “free speech absolutist” absolutely believe those who agree with them should be free to speak, and anyone that might affect them negatively or just disagree should be stopped from oppressing or endangering them. The term usually means as little as the “democratic” in DPRK.

A true free speech absolutist would not be concerned with paid speech being blocked, in fact they should really be against paid speech, at least in the sense being discussed here. The point of free speech is to be able to say what you want and saying something else because you are paid to, because you can't afford to turn down the payment to say what someone else wants instead, is anti-free-speech.
