It is censorship. And it is censorship by a government-owned mass broadcaster.Choosing to remove a song from a particular playlist is not censorship. They're exercising their free speech in taking a stance on the content in the song. They're not pretending like it doesn't exist or keeping anyone from actually hearing said song, or hiding it. They decided to keep it off of their own playlists for ethical reasons.
Nothing is stopping anybody from playing it in the comfort of their own home or from knowing the song or its history.. or from playing it out in public.
Your definition of censorship is so narrow that you would need a Gestapo-like force to break into your house and burn your LPs and destroy your computer.
Or unless robots wipe your mind, it's not censorship.
