Re: Do people care?
Over time people simply become resigned to things and, after enough time, no one will have ever known it any other way.
We know we are being watched and tracked by numerous means all the time. That horse has bolted and one more coming out the stable probably doesn't really make things any worse.
There are risks, potentially great risks, but most people don't see those as great risks to themselves. At least not great enough to demand it stops. And, if we are honest that would mostly be right; if 'they are out to get you', they will, nothing will stop that.
For some, being offered a menu app is an intrusion, for others it is welcomed. I would quite like my phone to tell me when the next bus is going to arrive when I reach a bus stop. Though I would want the option to enable it or not, and not be asked at every bus stop I pass.
I think it's going to be intrusiveness which causes more outcry than tracking, though battery drain from forced-enabling GPS, losing functionality if you won't, is a very reasonable and legitimate complaint.
The situation now is many people want the good but don't want the bad. Over time that 'bad' will become seen as just something which is and people will adapt to it. How many CCTV cameras have you been watched by today?
