Sony has created or attracted plenty of multiplayer exclusives this gen.
Little Big Planet 3
Planetside 2 (also on PC)
H1Z1 (also on PC)
Street Fighter 5 (also on PC)
The Last of Us
MLB The Show
Sony has a large variety of exclusives and lately Sony's single player exclusives have been receiving the attention but that doesn't mean they don't have multiplayer. They have more exclusives than the competition which is why I think the narrative of "PS4 not having multiplayer exclusives" was a lie created by fanboys to move goal posts to try to prop up Xbox.
While there are plenty of them that I enjoy, I would comment that many of what you listed are niche(Knack,Driveclub, LBP), poor performing(RiGs, Killzone), or actually developed by 3rd Party (Bloodborne, Street Fighter V).
None of these game's multiplayer component are pulling in Overwatch, PUBG, or Halo kind of attraction.
