i think you guys are mixing the morality with the legality of said actions.
i don't see having a copy of a copyrighted software that is 1) bit by bit alike 2) different in parts but substantially alike (same product, different versions) from the copy i already legally own, without paying the rights to own/use it (piracy) as immorale. i don't see that as immorale.
but i see it as clearly as unlegal. AND law is there to code and protect what is a system that largely conforms to morality.
