I definitely agree it was a strategy. No way Spotify thought they would get away with that, it's a PR exercise. The issue isn't Apple's 30% though - it's Spotify's business model. Apple charges all publishers the same flat rate. If you can't sustain your business on it either leave the App Store or force your users to register through your website. I can see how it sucks for Spotify but it is not unfair in my opinion (unless Apple had a monopoly on streaming music, then it would be anticompetitive but for now it's an advantage they have and should be free to use).
