What I meant is that one can't deny others those same 4 freedoms, which include modifying and distributing the changes.
I like to think that what folks refer to as its' "viral" nature is really the preservation of freedom. It strikes me that this license more than any other protects the rights of programmers and enables them to earn a living. This might seem counterintuitive, and it certainly is counter to the propaganda that often spread about communism and programmers earning a living, but much of that stems from the way corporations are structured as legal entities.
