What software are you talking about? I've seen very clever people struggle with PGP. In fact Ed Snowden famously screwed up when he first emailed Glenn Greenwald.
There's also keypair generation, which is the step that derails most people I think. Plus the fact that people have to grok the concept of public and private keys, and be able to distribute / not distribute them as appropriate. And revocation certificates. And public keyservers. And trust levels. Etc.
I do think an organised, disciplined group might manage to get PGP working as intended, but I doubt there are many such groups.
My point is, I doubt individuals implementing encryption have much to fear from whatever proposals may emerge from this. Maybe they will later. But it seems to me it's much more likely to target companies that offer/facilitate encrypted messaging.
Edit: Thanks to whoever just put my karma over 2000. Does anything exciting happen when you get to 2000 points?
Hmm. I guess my thought is that if it became well-known that using Whatsapp, iMessage, etc. to communicate about illegal activities frequently led to arrest, then knowledge of PGP and the like would spread because it's not too difficult to use. So then government would be able to read everyone's communications through those channels for no appreciable benefit.
