Right, and if the company depending on Homebrew had entered into a paid support contract, things would be very different. It's very clear that they do already give quite a lot of a damn about their users. I don't see how are you could get an impression otherwise. There are plenty of examples of organizations that do not give a damn about their users, but this is absolutely not one of them. Your argument seems to be something along the lines of "somebody at some point is paying them for some amount of the work they do on this product, therefore it is their duty to cater to every end-user complaint and request, no matter how capricious, misinformed, or selfish". I don't agree with that premise at all and I suspect that most other people wouldn't either.
