That is an exaggeration. There most likely will not be a dollar collapse this year.You can call it robbery squared... even if US paid $50 bil, that is QE infinity means as dollar collapse by end of year, its worthless anyway...
Once US taste success /blood from this method they will apply it to everything else, next target likely DJI. As you know, all they have to do is list DJI on the entity list, then Apple and Google are forced to delist the DJI Go App, then literally all DJI drones worldwide become useless, DJI brand image tarnished, value prop of its drones nosedive, and this helps US domestic drone industry like GoPro, Karma, Skydio etc
As for DJI, remember that people have already spent hundreds or thousands of dollars on a DJI drone
So they will go to the DJI website to install the app directly.
Alternatively, they could use another non-US appstore like Huawei or Alibaba for example.
Also, DJI has no direct US competitors since they couldn't match the Chinese hardware manufacturing supply chain in terms of speed AND cost AND quality.
Anyway, back on topic.
