While I agree with you that vendors need to be held accountable for shipping crap, we also have to beware that we don't end up in a world of devices we cannot do anything on.

All kinds of jailbreaks, no matter if for the first generations of iPhones, for consoles, or for rooting Android devices, are based on vendors implementing shoddy security. Take it away and whoops, now we as users are fully in the death grip of what vendors and RIAA/MAFIAA allow us to do.
