> Apple can do it because they lock you into their walled garden where they can double and triple dip on getting your money.

Nonsense.

It’s because they have all the expertise in-house anyway, they get extremely good terms due to their weight and negotiation, and they figure if you don’t change phone now you might do so next year and they’ll get your money anyway. There’s no brand loyalty on the Android side, and fostering it seems impossible (even brand recognition efforts don’t seem to do much).
