Earlier quoted context omitted.
I don't understand how this is a "feature". Is the price different, or the features gained different, or does it just determine who ends up getting what % cut? I can't imagine most people actually care whether Google or Spotify is getting a bigger piece of the same price they're paying either way.
The conditions and trust are different. I personally believe that letting Google have my credit card is allowing a kid with no supervision to play with my life savings; While some others will believe Google provides better guarantees than Spotify when you want to unsubscribe. At least competition will allow us to see “who’s better” and what T&C customers care about, and that’s the important point.
Given a choice of Apple vs. anything, I can't see myself choosing anything over Apple.
