Will once again re-up the concept of a “right to root access”, to prevent big corps from pulling this bs over and over again: https://medhir.com/blog/right-to-root-access
Most of users are not able to keep themselves safe in the internet - they want to install all kind of crap without thinking too much.
All of this is companies making it possible that average Joe could just click links, install any kind of crap and still be somewhat secure.
It's not always the user who's installing software. Lots of people depend on other people to manage their devices. Manufacturers like the hardware they delivered to be trusted so users trust it regardless of who handled it.
The entire Android OS has about as much access to radios than your average PC, if not less. In fact, even on recent android devices, wireless modems still tend to show up to the OS as serial devices speaking AT (hayes) (even if the underlying transport isn't, or even if the baseband is in the same chip). Getting them to transmit illegal frequencies is as much easy or hard as is getting a 4G USB adapter to do it.
