> Censorship is the suppression of free speech, public communication or other information which may be considered objectionable, harmful, sensitive, politically incorrect or inconvenient as determined by governments, media outlets, authorities or other groups or institutions.

YouTube is acting as a media company while pretending to be a platform. They're engaging in censorship since they're removing things on political grounds. Now, if the rules were always "no vegan videos, no violence, only kittens," it would be a different story.
