God damn it...I can't help but continually be drawn into this. You cannot possibly be equating non-GPLed software to slavery...or can you? That is, excuse me, the dumbest fucking thing I have ever heard.
Do you honestly believe that all software companies should just shut their doors, or give their products away by licensing it in such a way that everyone else can also release it(which is the same as shutting their doors)? I suppose you think that all artists (authors, musicians, etc...) should give their product away as well? That anything that anyone creates magically belongs to the whole of humanity? That it has no value at all? If you do then you are the most short-sighted individual I have ever come across. Money must be exchanged for services rendered (software, books, music) or they will cease to exist. It is not free to make them and somewhere along the way there has to be an exchange of money or the entire financial system breaks down (even worse than it is now). And before you pipe up with the mantra: "release your software for free and then charge for services!" please answer the following question: "Why in the fuck do you think your 'services' have a value when the software does not?".
