Apple can't acquire Homebrew. It's an independent, non-profit open source project and community and will remain that way. We collaborate with Apple and continue to want to maintain and grow that relationship.
There’s not much to tell. They provided us with a bunch of hardware for the Apple Silicon transition and we have contacts internally for both sides to help the other.
It's great to know that Apple acknowledges the project and supports it in some capacity though. Homebrew is definitely a key reason that I am a happy MacOS user.
