Yeah, we have been considering setting up a nonprofit org. I'm not sure if we have the scale to justify it yet, but it's sort of an open question.

Many states already have ways to file online for free. For example, Illinois: https://www2.illinois.gov/rev/programs/mytax/Pages/il-1040.a...

Definitely true. The goal is to unify the filing so that the user doesn't have to refill in their information for separate state and federal tax application websites.
