This is also my question. I think ruff is a great tool. I love it and use it on all my new projects. It is an insanely fast and enjoyable tool in a Python world where tools are frequently very slow and a pain to use. But how are you going to make money as a linting tool?

I will say that seeing from afar Charlie has been hiring some very smart people. Not sure how it will turn out but hopefully something good will come of it.
