Intuit's a public company, making both their revenue and the number of Mint users publicly available. They're not making anywhere near what they'd need to make off their extensive data holdings to make your theory work.
What I meant was, could you cite the numbers and math you are arriving at that tell you this? The 10-K I'm seeing says they make around $200M/year from desktop TurboTax and $2.2B from Mint and other services, and that's just with 20 million Mint users. That seems plenty to me.
