Well, Ubisoft are constantly bragging about how amazingly effective their god-awful always online DRM has been. But if that were the case, then there couldn't possibly be a 95% piracy rate for their games, because there's no way anyone in their right mind could possibly consider that to be a success. So they're clearly lying about something.
Personally, I pirate a lot of games. But only really when I suddenly get a random urge to play something (which happens often), but aren't interested enough to want to ever spend any money on it. For the games I genuinely want to play, I usually buy them. The exception to this is Ubisoft games - when I want to play one of those, I always pirate it, because, as a few people have already mentioned, there's no way I can possibly justify spending my money to support their horrible DRM.
