All I can say in response to this is that design is easier said than done. We didn't copy, we came to the same conclusions. I'm not saying those are the only conclusions, but we're not human-computer interaction theorists, we build practical things. Sometimes practicality trumps purity, and sometimes purity trumps idealism.

If you're criticizing us for not being perfect and not innovating enough, I can't argue. But don't assume (I am explicitly rejecting the claim) that we simply love OS X and want to make our own free version of it, or that we treat Apple as some sort of standard of "proper design". All I can do is invite you to come down to the trenches with us and see what it's all about. I think you'll find it's harder than you might imagine.

P.S It absolutely would not have been easier to find better categories. Those categories are the result of the manual naming tens of thousands of Debian packages going back a decade or more. We give users the option of browsing (as has been the tradition on the Linux desktop for the last 7+ years) by the traditional categories, or by using a free-form fluid list.

P.P.S Frankly, I find your dismissal of our design efforts mildly insulting, though I know you only meant to provide constructive and thoughtful criticism (which I appreciate, at any rate). A bit of constructive criticism for you would be to avoid assuming that because something seems like an obvious solution that it must have been the first or easiest solution. This can come across as arrogant and belittling, and has the tendency to undermine the constructivity of your feedback.
