God I hope this suit is successful. Lots of people here are discussing the regulatory trap they've got, and that's a big problem. But the actual problem mentioned in the suit is deceptive marketing. TurboTax is the worst in this regard.

Last year, I, at every step of the process, declined the expensive options that say "maybe you'll save more money if you permanently switch into this paid mode". Yet after a couple hours of filling out forms, they said at the end that it wasn't possible to file using the free version, and that I would have to pay a couple hundred dollars. That ticked me off. They have all of the information required to figure this out much earlier in the process (income), yet they continue to allow you to pick the free tier up until the very end where the tedium of starting over with a different service is too high. Fuck em.

Their UI is very nice though, especially for guiding people through a process that they almost intrinsically hate.
