Re: worse as Facebook
"I deleted data on a. Google account, and it was actually deleted"
First, how do you know? Second, that doesn't help with all the data the Google collects on us outside of a Google account, nor does it help with Google's non-internet spying (such as all that brick-and-mortar credit card usage information). Third, deleting that information does not stop Google's data slurping.
All in all, the ability to delete the data associated with a Google account is nice, but very weak sauce. It in no way is enough to put them on a higher road than Facebook.
