It certainly leads to a little speculation on being able to vet and audit hardware and software before putting it into production.
Although, truthfully, what's the stake of the NSA/CIA/FBI for tappping many miners in the first place? It would just lead to a lot of noise and greatly increase discovery.
I honestly don't care much, NSA has always wanted to monitor communication devices (the phone) and anything involving potential risks. They even spy on gamers because terrorists are using the game to communicate.

Then again, I guess we all would figure it out and come up with a solution faster than they ever could keep up with,
