It was more than a library of prewritten css, though, they did quite a bit of engineering work on tooling (speeding up the code scans and dynamically creating custom classes, etc). I respect the team's productivity.

This is more a question about the business model of open source, which has always had some challenges. I don't think you can support OSS with premium templates, training, and support once the knowledge is baked into LLMs.
