Isn't the concern with DJI mostly the software (artificial flight limitations, phone-home ability, ability for China to lock you out on a whim). I'm not concerned that the motors and carbon tubes on my drones are made in China, I'm worried about truly owning the device I'm flying.

If I were a Ukrainian DJI pilot I'd be worried about China doing Russia a favor by releasing a firmware update with this logic:

1) drone is flying in Ukraine?

2) motor amperage is higher than normal (probably carrying a grenade)?

  If 1 and 2, just return to takeoff point and drop the grenade

Maybe mix in a rand() so Ukraine doesn't catch on too quick.
