I used to be involved in building and shipping research robots (from Canada) and I remember we ran into this a few times with a bog-standard industrial wifi radio that for some reason was under ITAR. Interestingly, the manufacturer of the radio was set up to ship it directly to our customer, we just couldn't integrate it into their robot and ship it from our facility. So they had to put on the radio themselves.

The whole thing seemed very silly and theatre-y to me.
