Software is about choice and productivity. It's great that we have choices and I embrace a variety of them throughout my personal and professional life, but this "us against them" philosophy belongs in a boardroom and not in the hands of users and creatives.
We can say Ubuntu has come a long way (and it has) and that it's done a lot for gaining mind share (bingo), but a huge turn off for me in OSS is this "us against THE MAN" philosophy, why can't software just be software, a means of expression that you gives you choice?
