Re: Watching the watchers watch the watchers watch
If people were really concerned, or informed enough that they have the choice to be concerned, snoopy programs would not have the success they currently enjoy.
Since you bring it up, there is the small matter of lack of choice.
If Joe Bloggs wants to buy a phone or a tablet he has the choice of Android or iOS, both of which (though one vastly more than the other apparently) collect and use personal data for their own purposes. And with Android you get all the manufacturer and carrier cruft on to
If Jane Bloggs wants to buy a computer she has the choice of Windows, OSX or Chrome*, all of which (though one possibly less so than the others) collect personal information for their own purposes.
For your average person-on-the-street, there is no 'take my money then leave me alone' option. The option not to be tracked and profiled simply doesn't exist. Yes, some things do less of it than others, and yes there are options to tone it down (partly dependent on where in the world you live) but turn it off altogether? Not a hope.
*I was tempted to put Chromebooks in with phones and tablets, but online Office (etc.) is big on 'proper' computers now, too, so I think they live in that category
