In a world where competition exists, this is simple - one publisher can carry one author, other publisher can carry others and you just buy the content from the one you prefer.

In a world where everyone defends consolidation into monopolistic platforms and you need to choose which tech platform will own your life this becomes a problematic political issue. At least it's convenient right?

I don't see any evidence that NY was blackmailing Spotify. Wouldn't that require NY to be threatening to release some kind of compromising information about Spotify?

I think we both agree that he did not only make threats, but also follow up on them. Weinstein could also have made arguments that he never threatened any actresses to sleep with him, he was just withholding jobs from the ones who didn't. Call it the way you want, but the guy clearly abused his position

The difference being that one of those examples is illegal.

and the similarity being that both are immoral

Tying market participation to conditions within said market is just doing business, almost prototypical even.

I haven't seen NY saying the spotify CEO won't see their kid again unless Rogan disappears from the platform - that would be blackmail.
