"If you are being targeted even the Rasperry Pi you just ordered might be compromised." Is that like owning a car and having some third-party (who?) remotely cut the brake cable because the manufacturer fitted that "feature" in stealth? Or maybe they did something more benign (ie disable car speakers) just as a reminder as to "who is the boss?"
