> If you are hiring the Homebrew dev, and your devs currently use Homebrew, why wouldn't you hire him to work on Homebrew for you?

Macs account for something like 8% of the total marketplace of all PC's. For developers, they account for something like 20%... another 20% on Linux, and remainder on Windows or other.

So even if somehow having a paid Google employee work on Homebrew seemed advantageous, it would only benefit 20% of Google's staff, and 0% of the company itself (all Google servers are Linux).
