Frustration is the mother of open source and has always been. You have a problem that is solved in a deficient way by the free market (which is not free as in beer or as in speech, it's free as in fall). You think to yourself: I can do this better. You start working on it but quickly realize you really can't do it by yourself. So you enlist a bunch of people to work on it for free (as in beer) in return for complete freedom (as in speech) to divulge what you have collectively built.
Frustration with the free market, though, is not limited to software products. Anywhere you find an oligopoly there is frustration, and that's pretty much in the entire community and culture these days. People express frustration about the art they are perceiving ("The Crap That Comes from Hollywood"), about the roads they are driving, but most importantly (because I have an idea on how to solve the frustration) in services.
If you've ever used a cell phone, please tell me how satisfied you are with your provider. I am with Verizon, which has a decent enough network, but which thinks any reason is good enough to gouge my eyes out in extra fees. $3 for a ten second clip of a song as ring tone? Verizon, you should be ashamed of yourself! $36 for activating a phone? Boo!
