Since it’s free they were never sold to you as product, their asses are covered on this one, you can make an arguement for Elder Scrolls Online, Black Desert Online (I bought this one, I have the receipt to prove it) and Guild Wars 2 since they use the b2p model with an optional subscription. Car licensing can only prevent ubisoft to sell the game, it’s not required for them to shut it down and render your copy unusable.
