Well someone surely investigated the market, and determined that DJI owns most of it. So it would be an easy target to twist arms and shake out some dinero, into lobbiysts' pockets
What's really idiotic is that DJI made this list with no audit, no investigation, nothing. Just politicians stoking the China fear. As always, they don't care about anything but themselves.
That's my fear; when we do know it will be too late and I'll be stuck with a doorstop. I won't underestimate the stupidity of politicians who want to stoke fear to score political points.
