Not core to their actual revenues but it'll help massivly in knowing who are real users. Easy to automatically fake gmail/google plus accounts that look realistic. An account with real payments going to/from it is likely to be real, and can be tied to all their other services. And obviously when paying for things on youtube (which will become more popular soon) it will be as easy for youtube/gmail users, as it is for iOS users to pay for in app purchases.
