To be honest this has been a long known thing. They just modify the cookie instead of wiping it so that when you visit websites that are facebook enabled (ie comments etc) you can comment / like without having to do the whole login process. Heck they've done this for a few years now which is what the whole thing in Germany was about that occured recently.
Yeah, I find it annoying that (IIRC) you go on photobucket it seems to always sign me into facebook, pretty annoying.
What I find more annoying is that it recommends RL friends to me even though I'm on an alternative e-mail address.
Why is it such a big deal anyway. It's not like you've got some dude following you around everywhere. They have so much data they will never get the opportunity to solely focus on everything you do. People bitch wayyyyy too much. Pretty much every major website does this on some scale.
I'm only quoting this from someplace else as I can't find the link at the moment, but supposedly a guy went off grid for two years. No internet, no phones, no credit cards, lived in a caravan moving from place to place. At the end of it all he asked them to see what they could dig up on him and apparanatly they had a desks worth of information on his which was mostly from Facebook, so yeah. But it seems they got around to "fixing" the issue - http://www.bbc.co.uk/news/technology-15091674
