This is a weird pattern accross OpenAI/Anthropic to buy startups building better toolings. I don't really see the value for OAI/Anthropic, but it's nice to know that uv (+ ty and many others) and Bun will stay maintained!
There is the literal benefit of "we use the hell out of this tool, we need to make sure it stays usable for us" and then there is what they can learn from or coerce the community in to doing.
