Just a nit-pick, but the suppression of speech by a private institution is still censorship, it's just not government censorship. I think maybe you were conflating it with the First Amendment, which applies only to the government and it's agents and not private companies.

In agreement with everything after your first sentence though.

Yes, it was a poor attempt of trying to explain the common misconception that the First Amendment applies to private business. You are correct, though, the word censorship is broader than that.
