I don't think I said anything that disagrees with your post. Except for one detail - the comic you linked writes (emphasis mine):

"It's just that the people listening think you're an asshole, and they're showing you the door."

But as I think you'll agree, the problem is that "the people listening" often don't show the door (that's why hateful accounts gain such large followings), and it's up to the corporate owners to do the deplatforming.

But I agree it's better PR to describe it as "people" doing it. The manufacturing of consent necessary to maintain our democracy is much easier if we trick "the people listening" into thinking they are doing it, instead of it being done to them by 3rd parties.
