I hope you mean free as freedom. I'm not surprised that Pico is not open source. It's still in development and author is really careful about design and building a community around it. Pico is such a creative environment thanks to its limitations and last thing community needs is fifty incompatible forks that would change pallete, resolution or token limit :)
