That's just payback for the shade Sony threw at them on the last gen where they showed how to share games by just giving someone else your copy, whereas on Xbox you had to do some sort of library setup and checkout procedure before your disc would work in your friend's unit.
I wish MS would also poke fun at Sony's "We believe that PS5 games should take advantage of the new capabilities and features we're bringing to the platform" statement attempting to justify why PS4 controllers won't work with PS5 games, meanwhile most launch titles are cross-gen or might come to PC.
