I mean. This is what Ubi have been doing forever. Just about all of there games allow you to link with Ubisoft connect for some little in-game tchotchkes. But they never require it. I remember getting the Altair outfit from it way back in Assassin's Creed 2.
It's not like Ubi are new to PC gaming like Sony is. Doesn't make sense for them to change tact now. This is just an easy win for them riding off the back of Sony's blunder.
