Bullshit

>>So the idea is to piggyback on GCC's popularity to raise popularity of D. In this case it
looks sensible from FSF to require copyright assignment: why should it promote something it
can not control ?<<

Because helping D would allow to make better Free Software?
That's a Win/Win proposition IMHO.

While D is still young, it has the potential to allow programmers to make better SW than C++
(for an equivalent effort).
