The UK parliament passed bill to outlaw encryption

Wrong.
What they certainly want is hardware based backdoors, independent of OS

All future CPUs will be backdoored on both mobile and PC market (some already are), you can’t remove or fix CPU of your device.

Unless i miss something, the only way around that would be to use fully FOSS hardware + software like RISC-V + GNU/Linux, and be 100% sure that your contact using the same as well - otherwise you don’t have secure communication if one side will be completely deciphered on hardware level - both sides are in danger.
