No, it isn't. Think of G as an oil company that owns and operates a pipe from the oil source (user data) to countries that need gas and other oil products (companies that pay for targeted ads). G employees have access to a lot of knowledge about how this pipe works, but make no mistake: any attempt to look into the pipe will be retaliated viciously. Employees are strictly not allowed to look at personal user data, even though they can do so by writing a simple SQL query. I really doubt that G sells raw user data. Not because it's kind or nice, but because an oil company makes more profit margin by selling oil products, rather than crude oil.
