Android is becoming more Apple-ized everyday; it's horrible and more and more APIs get neutered or disappear, further limiting functionality available to developers.
Even if Android is as closed as iOS, it will never be the same. Cos business models are different. Google's business is behavioural ads. Apple's is hardware. And even their software services depend on that hardware.
It's worse than Apple because not only are they locking it down in the same way but the whole thing is funded by adverts.
