Well stated, but I will say, it is not impossible to do both.

Tantacrul is my favourite (and, actually, only) example of this. His work with MuseScore, with Audacity, his videos about them, and his takedowns of Sybellius etc. all opened my eyes to the world of designers who do things with hard-nosed analytical thinking, user studies, good principles, and make something useful. Even his little digressions about Paint3D and Ubuntu's Mobile OS are illustrative.

You are right but man the new Fig Newton packaging looks just like the store brand fruit cookies what were they thinking?
