Hardwired software or functionality imposed by companies or authorities

[ryo]

Another big example closer to home is an alert system that was discussed a few years ago if I'm not mistaken; Something that allowed authorities to track where your phone is located, and if you're in an area where a calamity is happening they'd have the ability to force a message on your device and you couldn't disable the thing. As an optional service I'm definitely not against it, quite the contrary... but forced and hardcoded into my device, no way I don't want any of that stuff.

AFAIK this is done by pushing a text to all devices connected to a tower from which someone wants to send the alert. And triangulation of an individual is possible by checking nearest tower connections. It's not super accurate but enough. If someone knows your IMEI - you can be tracked.

The only true way of remaining private is by leaving your phone at home, and just bring a paper-based book with you to read on your train commutes instead.
