I think you're right--Apple shouldn't control/influence Spotify. The issue here sounds different: Spotify has to play by the same rules as everyone else on the App Store, and Spotify seems not to like that.
No they don't! There's no reason Spotify can't pull their app, run an ad campaign, put pressure on Apple, negotiate a better deal, any number of other things. If Spotify thinks they can claw back part of the 30% apple tax, more power to them.
I agree. My issue is they're getting the Senate involved and going for regulatory capture, which in general isn't usually ideal for long term competition.
What you're calling for is preferential treatment because they're an established player, which is quite humerous to me given how much HN loves "disrupters"
What's more likely, that people will give up their iPhones to use Spotify or that people will choose one of the other available streaming music services?
