It's always interesting to me how, the more an entity has shown itself to disregard the privacy and rights of it's users/customers/citizens/etc in the past, the more people are willing to extend the benefit of the doubt that they won't continue to do so on new ventures.
This will be abused, they will overstep massively at some point, people will complain, then they'll take a cosmetic baby step backwards, and possibly provide their users with a pixelated cow icon to make up for it... then continue on their way.
I'm guessing everyone has already forgotten about the "we read your posts, even if you don't post them" thing recently? http://www.latimes.com/business/technology/la-fi-tn-facebook...
