What reason would there be to disallow it?
ITAR or even classified The robots are practically weapons. Imagine the 4-legged one chasing you down like a large cat could, then pouncing on you. Imagine the 2-legged one with armor, relentlessly stalking you like Terminator.
As an example of this, many autonomous underwater vehicles (AUVs) are subject to export control laws. This isn't just because they can be used in an explicitly military manner (one of the most common uses is minesweeping), but because the Inertial Navigation System they use while submerged has enough sensitivity to be export controlled, since that tech can be adapted to be used in missiles. So it's not the robot that's export controlled, but the INS system inside the robot. If you took that out, most of them could be sold wherever. I believe the same thing goes for a lot of satellite technology that's export controlled.
The robots Boston Dynamics build seem to be solving a different problem, the (very hard) one of physical adaptive control in real-world environments, but imho what I've seen doesn't line up with what often seems to the reasoning for assigning an export control label, whether ITAR, EAR, or even CUI, to most of the technology.
