As far as i have read, ubisoft had not the best sales with their DRM contaminated games.

So where is their advantage?


The fair minded purchaser of a game which has DRM is the loser.
The pirate is the winner, well he didn't give money for sure but the point is that the pirate doesnt have to struggle with DRM issues.

Publishers should invest their money "they waste on DRM coding" in persecuting the pirates on the p2p plattforms and others.

That doesn't negatively effect the sales like DRM does, because it's not against the purchasers, but lowers the pirate rate.
