Someone shared on Trisquel's forums a direct email communication with Purism revealing the way the company avoids being fully transparent about the fact that their device does not offer better privacy when used *as a phone* — it has privacy advantages only when the phone functionality is completely turned off, in which case the questioner claims it is nothing more than a pocket (or even stationary) PC.

there was a court case in NY in the early 2000's where a mob boss got convicted based on evidence gathered that way
it wasn't a phone software thing, it was functionality of the hardware (think Intel and there above the OS mode)
