The censorship issue is one thing, yes both companies apparently care about what they agree to distribute through their "Apps" service, and I personally agree that both companies should have the ability(or right) to control what they supply through their portals. I find fault on the issue of device ownership and what you are supposedly "allowed" on the device. To me it appears that the google approach seems more like the pc market, which I'm used to (buy device, put what you want on it, with some restrictions) but it's more complex because google doesnt create all the devices, just the OS. Where as apple (mobile stuff) is not quite so accomodating with respect what you may want to put on it.
Oh, I didn't say it "was" breaking a law, just that the possiblity exists, and yes apple shouldn't honor a warrenty if the the device is tampered with, the risk is too high, but then that leaves you not having an app you may want which is what I was saying, "they make it Hard" to get an app you may want.
In the end, it just business philosophy, and the apple, with all their restrictions and crap I dislike, seem to have made a good choice on how they want to run their company, at least finacially.
