If you are that particular about your tools you should consider making them yourself, or using software you can really claim ownership of. iTunes and Chrome are not your software in any meaningful sense. Even less so probably because they are free (gratis).
With Mozilla you might have a claim, and I assume you are free to make your own version that has the columns in your preferred order or whatnot. For official support you just have to convince a sufficient number of like-minded programmers that yours is a problem worth solving, and then some minor technical bits like "What determines the central theme?" and "What scripting language shall we standardize on?"
If my hardware (hard disk) has a particular configuration of bits stored on it then they are my bits. How can information stored on something I own not be mine? I'm not talking in the legal sense here, I think that patents are ridiculous, but in the common sense sense.
I can't tell if your original comment was more than a rant. In some sense you own those bits, but not in a way that is useful to you. Starting with just the bits, it's going to be a lot of work to make iTunes skinnable, and you likely won't be able to distribute your changes legally.
It seems similar to ranting that Miles Davis has recorded all of these long boring solos on _your_ CDs. You could spend your time editing them out, you could demand an edited reissue from the publisher, you could just listen to something else, or you could learn to play trumpet and record something you'd rather listen to. The least useful option seems to be posting to HN.
