If backdoors legislation is passed, would there be any economic effect? Personally, I wouldn't be interested in doing anything more than "basic" stuff with my phone and would not feel compelled to upgrade phones so soon.

As for computing devices, aside from proprietary systems like Windows and Macs, do we not have reliable options that allow us to use uncompromised encryption?

Whats to stop app developers for embedding encryption packages or would they be forced to use compromised solutions?

Can you stop a person from building a secure line over a compromised medium, if that is even doable?
