What is the espionage device in my pocket actually going to do to me on my day to day life of browsing Lemmy and playing music?
In your case its not so much the device in your pocket, but the telecom switching gear on the backend that all that corporate and government data flows though. Huawei makes lots of that gear.
In specific cases of phones, while your job may not be high value for espionage , there are lots of people that do work highly sensitive positions. If the specific handset redirects email, txt, or phone conversations then that would be a problem at the national security level.
