In my opinion, governments worldwide need to get a grip on this tendency to corporate snooping, and make it absolutely clear to corporations, via legislation, if necessary, that corporations exist to serve society, NOT the other way around.
Unfortunately, the government also wishes to be able to track your every movement. If they try and mandate it, people will revolt.
But if people, especially the younger generations, get used to it in little bits that don't really seem that bad, then why not?
We already have the "people who brought this also brought" type of not-quite-tracking ads on various sales sites (eg ebay, trademe etc), we're placing ident chips in our pets and on our crims (well, gps trackers anyway), you can buy gps tracking watches for your kids (so they grow up used to the idea of their every movement being tracked - and any crim kidnapping your bratling will, by now, know to toss the kid's watch, phone, and any other electronic device out the window as quick as they can just before a sudden direction change).
Each step is a little bit closer to constant tracking of purchases and movements. Then there will be a massive "privacy breach" and instead of all this stuff being shut down, a special government department will be created - Department of Privacy or somesuch, which will exist "to handle all this data and make sure it's handled by the right people because clearly we cannot trust the corporations to do it", and the populace will lap it up while laughing at the few tin-foil-hatters who say it's a bad thing. And of course, as sales are global now, this will be a global "department" with data sharingprivacy monitoring between all participating countries.
A few "terrorist" governments will not want to be a part of it, but we will soon send in our righteous air force to blow away their nasty chemical weapons labs even though the video footage of the attack that caused outrage seems somewhat suspect to said tin-foil-hatters. And as a result of the outrage, it will be time to send in our forces to take out their democratically elected evil terrorist government.
