Its hard to predict how a good open source tool that solves hard and painful problems will evolve in a marketplace. I don't think Linux developers would have remotely dreamt of a cloud revolution when they were creating an open source kernel. Maybe windmill will enable a marketplace of automation tools that can be leveraged across multiple business for multiple usecases. Never underestimate a open source solution solving painful problems.

You are argument is fair but being a VC backed company puts a deadline on the org. They have to not only prove that it solves a pain point but also make a ton of money and growth.
