It is Ubisoft.
You need to send in a blood sample, to be considered as a potential costumer.
If they decide that you are not pirate scum (which you are flagged as by Ubisoft by default, when gaming on a PC), they send out a guy with a retina scanner - to keep your credentials for logging into Uplay.
You must of course be online always to play a single player game, so they can keep track of your whereabouts at all times.
If you complete the above steps; you now have access to 15% of the game, and must buy 311 DLC packs and a Season Pass to have the whole game, which by the way does not really work.
You are now renting the game from Ubisoft - since you cannot claim ownership of digitally distributed games.
Have fun!
