I haven't checked in a while, but with Apple you used to have a much better chance of people shelling out money for/in your app.

They only have that share because developers continue to support their platform.

Too bad developer greed prevents an effective boycott of their ecosystem. If enough people stopped giving them money, they would change.

I think it's a bit more complicated than greed. Remember that the only mobile development shops in town are iOS and Android, and they're both run by tyrants. There are millions of developers who only know mobile development. Giving up their skillset to learn a whole new profession is difficult.

Your criticism essentially boils down to "Too bad human behavior is the way it is". Sure, I agree, but it's pretty unactionable.

To go further, any competition to Google and Apple are killed in the cradle by developers refusing to support their platform.
