Technically, you're right. Media in America is dangerously moderated and by too few individuals. However, the argument being made here is that it's not censorship if it does not involve the threat of force:

The only true censorship is when government agents approach these companies and demand content be removed under threat of force or violence. Provided these companies are not under any kind of threat, there can be no censorship.

While that is an extension of the term's general use, Dantheman is careful to explain that it's necessary to specify so that we don't "talk past each other." It's always most effective to respond to writings in their own terms. It may be that you're just using the visibility to champion an unrelated cause, but I'd be careful about seeming to muddy this post's use of the term. It has been made clear to keep people from mislabelling, on Steemit, what is not censorship, on Steemit. Sorry to be pedantic, but it matters.
