Earlier quoted context omitted.
It's definitely economic protectionism but it's mostly protectionism for national security reasons. I assume the US is going to start manufacturing drones for war in large numbers in the near term and they need to be made at home (or at least by allies).
Yeah the thing is that the US always, always justified everything by using the "national security" excuse/narrative. When another country does it to the US and its corporations, which has by far the longest modern history of getting involved in other nations national security, then it suddenly becomes an attack on free trade and pure protectionism.
Is it any different than China wanting data access from U.S companies that attempted to open their business there? I'm not in favor of this ban. I think they should've at least forced DJI to keep the data local before going for an outright ban.
