I think that many customers have been relatively resistant to changing their tax software. Customers who already hate figuring out their taxes are loathe to introduce yet another element of frustration by hopping to a new software brand once they've figured out the peculiarities of their "ol' faithful". For some people, it's a "sticky" product--like changing a primary checking account or changing email addresses, they consider it a PITA and are willing to pay higher costs/suffer with an inferior product rather than go through the hassle of changing. Intuit has counted on this to repeatedly raise prices (overtly and also with stealth price increases as we just saw). They've depended on that for years, and pressed for all the increases they can, now they are significantly more expensive than HRB and TaxAct.
If a large body of TT customers have now overcome the "stickiness" and realized that other good products are out there, and that switching is easy, I think Intuit may have done some real damage to their sales and their pricing power in the future. That's good for everyone who buys tax software and who benefits from competition in this marketplace.
