I received an email a while back from them basically saying they were going to start taking privileges with my data if I didn't go to a page and opt-out. I don't remember the text, but that was the gist.

[Edit] Did some digging and the email subject was: Important Update Regarding Your Privacy

It has various sections on what will be used and how with a call to action at the bottom listing your options.

Opening text: Why am I getting this notice?
