Seems a bit Orwellian to me. Freedom is Slavery, War is Peace, Ignorance is Strength.
Yes, it is Orwellian. That's GPL propaganda for you.
Here's real freedom:
You may copy, modify, and distribute as you please. In other words, what the world would look like without copyright.
Here's GPL "freedom":
You must release your source along with your binary.
Now you may agree or not if that's overall good for society, but that's an argument for consumer protection, not "freedom". For example, I may very well like the idea of government food regulations, but regulation is the exact opposite of freedom.
