I've started doing the same. Of course, I wouldn't be shocked if either or both of the following were true:
1. Other countries collude with America in this practise; 2. Other countries are also practising this.
Open source is a potential solution to this problem. It doesn't guarantee security (heartbleed anyone?), but it does allow anyone, anywhere, any time (assuming capability) to verify. My router runs Open-WRT, so I feel safer.
