I spent years working with the FAA to get a local airspace transitioned from a Class E Surface to just Class E so we could do drone stuff there. Then we went to fly our DJI, and it wouldn’t let us! After digging in, we found that all flight planning involved a round trip of the data to servers in China and back. They hadn’t updated their maps of US airspace on those Chinese servers and thought it was still Class E Surface. So China shut down our drone. When it wasn’t shut down, it was recording the track. We were doing defense work with it.
This was some 6-7 years ago now.
Similar with Bambu 3D printers, sending your data from the design software on your computer in your shop to the printer sitting right next to it means your data takes a trip all the way to a server in China and back. There are ways to skip that, but it involves more effort.
