Hi Tomek, If NuttX continues to turn away new contributors, it will become increasingly difficult to use professionally.
I personally had to submit 29 PRs just to fix and adjust the ESP32-S3 support. It is very hard to justify using NuttX to commercial management with statistics like that, especially when Zephyr is heavily marketed as stable and production-ready. We need more people actively contributing, testing, and refining code. Many implementations start out unpolished and are refined over time. I am genuinely concerned about the number of new contributors appearing only to be blocked.
