This topic is not constructive because you just ignore what people wrote to

RMS is very different from "the CEO of a large proprietary company". His
objective is social/ethical and not financial at all. RMS makes a *very
modest* living by defending his viewpoints. Given his exceptional technical
skills, he would be rich today if he would have gone to the path of
proprietary companies.
RMS does not "need you to buy his product". Otherwise he would precisely do
what you seem to regret: he would not "badmouth" large companies so that
these companies invite him.
His viewpoints are *separated* from those of the FSF. They are on
stallman.org and go far beyond free software (whereas the FSF exclusively
focuses on free software).
