Great article. Really puts into words many complaints I have against Homebrew. The non-sudo thing doesn't bother me, its the leadership. User-hostile is definitely the way to put it. I don't anticipate leaving Homebrew any time soon, but it sure would be cool if the maintainers were nicer. A favorite thing to say is that they don't owe the users anything, but I think that they forget that a lot of users are contributors too.
And they would probably contribute more if the maintainers were a little nicer.
