If what you say is true, then GPL license, is not a so effective virus, it could work in a more eficient way... and because I'm very little altruist, I think that virus is eficient.

If this addons are legal, even if they don't use previosly programmed GPL code, then what we are discusing about is legal too. There is no difference between first brew GPL code and previosly programmed GPL code AFAIK. Both have the same "rights", and could be used the same way.
