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
