Google's revenue per user is unfortunately much higher than $10/year.
So for less than a Netflix subscription you have Youtube, Gmail, Search, Drive, Translate, Calendar, Maps, Photos, Hangouts and more. Services that many people use regularly.
It wouldn't be hard to argue that any of these products is worth a lot more than $10 a year, but convincing users at large to go down that route will be a challenge, undoubtedly.
(Also, many users would agree on the value but balk at redirecting funds from an existing allocation to continue service on something they've already gotten for free.)
