If all they did right now was leave Ruff exactly as it was and walk away they would have given the Python community a great gift.

Sure, it’s rendered a bunch of projects obsolete, but it’s because it’s so much better than the predecessors.

If they stop development on Ruff today, Ruff won't be useful anymore after a few new Python releases. If the maintainers of the tools that Ruff is replacing stop maintaining them, the whole Python community will be in a really bad place. So, there is reason to be cautious. Astral being transparent on how they plan to make money would be very helpful.

I do get the caution, but I think that even in that case there’s enough momentum behind Ruff for the community to fork and carry on.

Obviously it would be pretty crummy to end up in a situation like pyright where MS really have leant in to their embrace, extend, extinguish strategy.

That is true for every single development tool in the Python space.

People could just fork it if that happens. Since the foundation of the tooling is solid, I 'm sure the community would rally around a fork that keeps it going.

“People in the Python community”?

Yeah. Probably precisely the same people that call everything EEE.

You’ll always find people acting alarmist about anything.
