Instead of Ubuntu doing Ubuntu4Android (with their cell phones), they should write their own Cell phone OS. Basically, just a scaled down Linux.
The only hope we as people have is something open.

They have it is called Ubuntu Phone.
http://www.ubuntu.com/phone however Ubuntu for Android will force the Android part to be open because of all the third party GPL v3 code in Ubuntu. A (GNU, Android or both) / Linux based phone OS, where the end user controls root will allow the end user to lock out the manufacturer and the telco and consequently any government or third party snoops. This does not affect the fundamental security of Bitcoin, other than the end user should run Bitcoin on a secure OS where the end user is the only person in control.
