what are you talking about? the devs will NOT use denovu, as far as i see it
GOG would be a fitting platform for the game, considering the DAY-1 patch and other updates are gonna add the rest of the content which got pushed back by development cycle
Piracy did nothing to the sales of the witcher 3, i don’t see how being DRM-free could harm the sales of this game
If GOG is selling something they shouldn’t, it is a matter of few minutes to inform the game’s publisher a.k.a rightful owner and they will happily rip GOG apart.
