The OP is from an already-existing open mobile OS, which already has a deal with a manufacturer. The problem isn't, and has never been, making an OS. This is not a technical problem. This is a political problem.

But that open mobile OS is still a fork of Android, which is too hell bent on privacy (which is not a bad cause, but something that masses don't care about). We should focus on an OS which is hell bent on UX, UI and other features that masses crave.
