There's permissive and then there's exploitable. People who benefit (financially) from being able use other people's work without contributing their own changes would prefer us to call it "permissive" instead of "exploitive". It's sad that the movement which originally democratized computing (by placing development tools into the hands of ordinary users) is slowly being changed into a pyramid scheme that fleeces volunteers. So, to echo other comments in this thread; GCC keeps the corporate BSD crowd honest, and postpones the day when they lock up their code.
