Wow this is totally bad.
So GOG basically downloads a crack from the internet, cracks the game, removes the signature and then sells it?
This doesn´t sound too good. I always thought GOG changes the source code to remove the DRMs present.
When the source code is available, they do actually do that, but sometimes original source code is no longer available, especially in the case of really old games that have very likely changed ownership several times over the years. In those cases, the only way to deal with the DRM is to either crack the code themselves or resort to using existing cracks. Why re-invent the wheel? Many existing cracks are very professionally done and are proven effective, so they just use them. This is completely done with the original rights holder's permission and knowledge (in at least one case, GOG stated the cracked version was provided to them by the rights holder) so there is no shady dealing going on here at all. Some people have a problem with GOG not "crediting" the crackers, but quite frankly, no one should really expect that considering the act of cracking the game without the rights holder's permission is illegal in most countries.
Wow, i'm - shocked! If this was true i'd completely loose my trust in that company. I mean, i pay for that!
DRM-lessness is THE prominent feature about GOG. I'd expect formerly DRM-protected games to be properly recoded, and not just cracked.
I really hope GOG would give a statement on this issue, or i'll resettle to abandonia...

EDIT - Hmmm. You probably meant an official statement about this particular game, not a statement about the use of cracks in general, didn't you?
