I get it when it comes to analytics, beacons, tracking outside of the ecosystem.
And the police don't seem to care at all, nor do their masters.
How is a global surveillance network and database like a Rolodex?
You're also likely to be using Google's DNS (8.8.8.8) without knowing, because some piece of software decided to hardcode that DNS server.
And your friends have almost certainly already uploaded your data to Google's Android backup service and to WhatsApp's database.
I'm not saying they don't take it too far, but certainly someone with an account has invited facebook to do some data collection and tracking.
ADD: I probably have 100+ accounts at various sites online. Do these guys all get free passes to collect data and track me because I happen to have created an account there?
Facebook certainly operates outside of even this rather liberal framework so I wouldn't defend them wholesale. However I don't like false equivalencies.
It goes further than that, as it affects other people too.

As a further point of fact, Facebook (and Google; Facebook is not alone here) stalks even people who _can't_ have a Facebook account. For example, children under 13 in the US.
Surely this is illegal, though? One way to get the laws to ban this sort of dragnet commercial surveillance of people would be to appeal to the 'think of the children' argument and ban companies from tracking information about anyone under 13. That would also stop them from tracking information about anyone that hasn't totally confirmed that they're over 13.
I don't know enough about the law on this to comment.

Tempting, though I worry about unleashing demons even if you think they're on your side... ;)
