Linus went on a rant yesterday about interpretations of the GPL. As he said, it's a legal license, and in my words, not some moral lesson to be learned at the end of an after-school special (RMS might think differently). Linus takes offense to the FSF defining what "freedom" is, and while I do think he's a bit jaded by the whole thing, I tend to agree with him. Personally, while I respect the GPL for what it is, and adhere to it where necessary, I never have, and never will never release any of my original code under the GPL. Quite simply, I don't like forcing users of my software to do something just because they've bundled or integrated my software into theirs.

I think it's great that we have so many licensing models to choose from. GPL is a perfectly valid option, and I respect it when I see it. I've just chosen not to use it for my software. Respect that.
