I kinda don't get your point, what difference does it make to "topogun" if he uses other free software(blender) instead of cracked Topogun and he succeeds in his goal anyway?
think about it. he'll be comfortable with that free soft already and there are even smaller chances for him to ever buy topogun,
whenif he cracks it and does the job with it, he'll eventually but Topogun, people like you are dumb IMHO,
I've bought many softwares because I've got cracked versions at one time and I liked them, and believe me many many people do that way, (who are making money with it anyway)
and all the people I know who love and adore Vray and now own it is because they had cracked version at some point,
