I guess that implies that Google did not know this before. If you are logged into GMail, are you not logged into Maps at the same time?
Also, I believe you do not have to be logged into Maps on your mobile phone to use it.
Lastly, what are we worried about here? The NSA can figure out how to do a join between all the different databases Google has to uniquely identify you and Google will not ask you for consent on that. What Google is trying to do is combine the info from various services to get better targeted ads. Is that exactly a tragedy or an invasion of privacy? At the end of the day, no matter how they collect it, store it, organize it, or analyze it, you end up voluntarily giving them all the information. Don't want to do that? Sign out of YouTube.
