Old Facebook trick - likely resetting that box each time the app is updated.

In all fairness this is someone saying something. Misremembering happens. Unless we have something with a bit more evidence, the simpler explanation suffices.

I wasn't aware of that, definitely a shady practice if that's the case.

At least when my computer's bluetooth exhibits this behavior (e.g: if you don't have a keyboard&mouse plugged in at boot, bluetooth might auto-enable), I can go inside the hardware and physically disconnect the antenna.

What am I supposed to do in software (perhaps hardcode config.file)? in cloud software services (??)?
