With Apple's devices, and to a lesser extent Google's, there isn't a software distribution channel apart from the one sanctioned from up high.
That being said, the official channels are sanctioned and sponsored by Apple (or Google) and so it is their reputation on the line when it comes to malicious or questionable Apps.
So I can completely understand Apple (or Google) removing certs or banning companies for violating the terms of their platform.
And I think this exertion of power might be a bad thing as it demonstrates that users do not really own their devices and are only allowed to do with them what Apple (or Google) permits.
