I get where you're coming from, but I think the open source community benefits from being, well, open. Walling yourself off from user frustrations and criticism with the attitude that they are ungrateful is not how projects evolve to better meet user needs.
If you are not happy with open source, you have a couple of options:
- build your own brew
- brew is open source, so you can make contributions to improve
- pay for something like brew (though probably not an option for brew)
Have you done any of the above before complaining? I am guessing - no. Otherwise, say "thank you" and move on, my friend.
