It's subjective. HFS+ is perfectly capable of being case-sensitive if necessary, so it's not a fault of the filesystem. He's just griping about the default configuration of developer machines. News flash: if you're a developer, you may have to think about how your computer is configured. You might as well complain how some linux distros don't come with emacs installed and calling it 'brain damaged design' because it isn't what you want.
