Not creepy at all
There is no expectation of privacy in public. This just drives it home.
knowing that the three letter agencies can do this same forensics to catch $badGuy is somewhat comforting that at least it can do the function it was meant. preventing everyone else from doing the same is where the wheels fall off the bus. it's another one of those situations where the intended purpose gets shoved to the side with unconsidered purposes becoming the norm which makes $tech look evil.
