It isn't a ban on everyone's devices just government devices. I don't want a foreign government like China to have easy backdoor access into thousands of government devices. That's a huge and unnecessary security risk.

The government calls them UAPs (unidentified aerial phenomena). While the government admitted they "exist" they have never confirmed any connection to extraterrestrials. They've listed that most of the sightings can be attributed to airborne clutter (in radar), atmospheric phenomena, US developmental systems, and foreign adversary systems.
