So now I am FORCED to download a crack (this counts for a pirated copy in ubi's eyes) for the game that I legally own
Hugely disingenuous of Ubisoft if they do claim that.
A crack is exactly that, a crack, all it does is remove DRM, it alone CANNOT be taken as an indication that any copyright violation has occurred, the copy may have been bought and acquired fair and square.
Downloading and applying a crack is not the slightest bit illegal or even immoral. No part of international copyright law depends on you purchasing a copy and only using it in a certain state. Correct me if I am wrong someone, please.
In fact it's also illegal (I am told) to ban someone from being able to play a game online because they cheat. Legally, the only thing you can do is segregate the cheaters from the non-cheaters. That would be interesting, having a designated cheater server where the cheats fight cheaters.
