I'm sure they told the CBP they'd get registered as soon as they cleaned up their logs.
The pre-install script I looked at reported back to iDS if it found dropbear on the system (and then wiped it out.) A nit picker could definitely pick a nit with them removing functionality already present on their unit with out asking for one's permission first...
Once they sell it to me, its mine. Theoretically I haven't rented the unit...
