Have they figured out yet how this VC backed company will make money? It's quite important imo, I don't want a watered down experience 5 years from now.
Charlie is on record stating that their goal is to sell value added pieces to their tooling and keep the core tools free and open.
Pydantic had a nice model where the open source tool is fantastic, but they now sell a cloud based logging system around that. There will be some enterprise tooling around UV that they could sell while keeping the tool itself free
It sounds like they're not yet at the stage where they need to worry about it, though I've heard Charlie mention making an easy to host package registry as one offering.
I would pay if they could make our GitHub CI run 20-30% faster.
