However, if you watch tech news much, you know there has been much furor surrounding this announcement. Personally, I am not suprised by what Google and Facebook do as their business is based on finding out about you, and then serving you with filtered content based on what you have shared with them. The issues arise when they are collecting data you did not intend to "share".
I am generally ok with thier changes, if for no other reason than to make sure there is a potential competitor to Facebook. I think there are legitimate worries that Facebook wants to BECOME THE INTERNET. They want you to come to Facebook.com and never leave. My preference is for a wider experience, and if Google can unify their myrid of products that may give many of us the alternative to Facebook that we desire.
Here is a video from Google explaning the change from their perspective.
