Thank you. I have so far gotten back very polite replies from Bob Meighan (Vice President, Tax Development, Consumer Tax Group), Brooks Fisher (Vice President, Vertical Strategy and Integration), and Steve Bennett (President and CEO). Bob Meighan's response was particularly detailed and extensive.
I'm not going to publically post our email exchanges, since I had not indicated to them ahead of time that I might do so.
If people disagree with Intuit's actions, it is important that they communicate that fact (and their reasons) to Intuit. After all, how can we hope or expect a company to correct a mistake unless it receives adequate feedback? Even if the sales of Turbo Tax suffer this year, it does no good unless Intuit understands why the dropoff occurred.
Intuit has valid reasons for wanting to suppress piracy. We need to motivate Intuit to find a different way. Free market competition can be an extremely powerful motivator.
