Free Software Business: "Remember that the GPL is not a mass-market license like many EULAs.
The GPL asserts rights that copyright holders already have under
copyright law, and then tries to condition your license on your
agreement to a lot of things which are, indeed, very "severe" (I
wouldn't agree about harsh or unfair).
The mass-market licenses we're discussing say that certain uses (not
reached by copyright law) of a product you've purchased, which you
would otherwise be legally entitled to make, are forbidden."
