> I don't really understand why anyone who claims to be a proponent of a free market economy has an issue with a private corporation deciding what type of content they want to broadcast.
Being a proponent of free markets doesn't prevent me from criticizing how that freedom is exercised.

It is censorship by any reasonable definition. It's just not illegal censorship.
