Respectfully, please read the definition of suppressed. "Removed" is not a requirement for censorship, that is just the strongest version of censorship. Censorship is the taking of any action to eliminate OR diminish the message of someone else.

For example, I enjoy listening to Dave Rubin, who is a mild speaking libertarian. When he gives public talks it is common for people of opposing ideologies to sit in the audience and begin making noises with bells or some kind of jingling thing. These people are not preventing Dave Rubin from speaking, but they are trying to diminish or hinder his message by creating distracting noises. That is censorship.

Taking an action to diminish the visibility of someone's message is censorship, in whatever form it takes. The only reason people are arguing against the dictionary definition is because they like to pretend they are not on the side of censorship when in fact they are.
