It's an interesting balance that Intuit is trying to strike. They want the tax code complex enough that people don't feel they can do it by themselves but simple enough that they don't feel that they need to hire a CPA. Since every filer is different, there will be some that fall on either end of the spectrum (though they have their free products to address the simple cases), but the goal is to keep as many people in that "comfortable using software" group as possible. What's truly amazing is just how little it costs to buy that influence. IIRC, it's in the $10m-$15m per year range, which is less than half of what they spend on hosting for TurboTax alone.
I've had conversations with Brad Smith (CEO) and Scott Cook (Founder) and often considered asking them how they can reconcile their "Integrity Without Compromise" corporate value with these kinds of lobbying activities, but I never had the stones to ask the question. I will say that from my interactions with them, I'm positive that they do have some rationalization in their heads that makes them actually believe that what they're doing isn't evil, I'm just not sure what it is.
