These tools are open source, if they lock them down the community will just fork them.
Nice idea in theory, in practice is how many folks down in Nebraska are going to show up.
as someone who works in the python tooling space I think you underestimate the number of people who would be willing to do this. i would personally help maintain a community fork of ruff if it got to the point where one was needed, though I draw the line at moving to nebraska first.
This might be true for uv and ruff, and hopefully that will happen. But pyx is a platform with associated hosting and if successful would lock people into the Astral ecosystem, even if the code itself was open source.
