• Me, I just don't care about proprietary software. It's not "evil" or "immoral," it just doesn't matter. I think that Open Source can do better, and I'm willing to put my money where my mouth is by working on Open Source, but it's not a crusade – it's just a superior way of working together and generating code.

It's superior because it's a lot more fun and because it makes cooperation much easier (no silly NDA's or artificial barriers to innovation like in a proprietary setting), and I think Open Source is the right thing to do the same way I believe science is better than alchemy. Like science, Open Source allows people to build on a solid base of previous knowledge, without some silly hiding.

But I don't think you need to think that alchemy is "evil." It's just pointless because you can obviously never do as well in a closed environment as you can with open scientific methods.
