Looked up the definition of censorship: the suppression or prohibition of any parts of books, films, news, etc. that are considered obscene, politically unacceptable, or a threat to security.

Some definitions have narrowed it's purposes to just "offensive", this one was slightly broader.

Given this meaning, Spotify's action is on the line of security and safety. JRE is taking heat for misinformation about covid, specifically about vaccines and alternative treatments, as well as his history of having platformed Alex Jones.

I'd say preventing snake oil salesmen from selling their products in your market due to safety concerns is a valid employment of censorship. People could actually die due to believing some of these extreme guests. Obviously, legally there is zero problem here since a private company can do as it wishes, freedom of speech doesn't give the freedom to dictate to companies what they must sell.
