I always feel weird when people talk about how restrictive the GPL is, how it's an attack on freedom, how many restrictions it imposes.
It's just that the vagueness of it reminds me of the Southern US states talking about how their Civil War was about "states rights". A vague cause that avoids talking about the actual cause. States rights to do *what*?
So tell me, the GPL restricts you from doing *what*?
I mean, the GPL only restricts one thing: hiding source code. If that's what you want to do, just say it: you want to hide source code or you want to help other people hide source code. Just say it. Enough with the "restrictions" vagaries.
