Free is too expensive (Economist)

It's lovely to not care solely about money, but it's awful to be antagonist about money. Even if it were true that money will corrupt even the best intentions eventually, until that happens you fight the good fight. It could take quite long time.

To use an analogy: Bioware used to make great games for over a decade, founded by people who were evidently very passionate about gaming, until EA bought them and apparently destroyed the company and its values from inside. No matter: I think that the world is still better for Bioware's existence, even if it never again made another good game.
