Re: 'take Android away from Google'
While I agree that the permission system needs an overhaul, the 4.3 "accident" was not the answer. It basically broke most apps to which it was applied.
CM has a privacy guard feature, which has worked much better from what I can see. I believe that, rather than just stopping the app from using those permissions, it fakes the responses somehow. The app believes it is accessing your files/camera etc. but it isn't.
To be honest, I think it was a mistake on Google's part from day one. The permission system should have been set up so that an app requested a permission, but the user had a right to deny it. The current system is that the app demands permission, and the only way to avoid it is not to install it.
Of course, if you deny an app permission for something it needs for core functionality, then it can flag that up, explaining why, and ask the user to give it back. For example, if you deny a web browser access to the internet, there's not much point. Another option would be to separate mandatory and optional permissions, and bring in a policy of only having permissions mandatory for core functionality.
I doubt this will get put in place. It would require a lot of reworking of both apps and OS. The alternative from CM seems to do the job well enough.
