Me! I care! I want to use the things I create and be able to fix them when they break without relying on an intermediary simply because I'm too lazy to learn. It gives me a feeling of contented self-actualization and overall satisfaction with my choices in life.
Perhaps that is overrated and I should focus more on exploiting people with crappy software so that I can make more money. I guess that's what life is all about.
Too bad we live in a society where goodwill, self-actualization and satisfaction does not ensure survival or pay bills, but rather gives you a competitive disadvantage.
