So when God of War, Spider-Man and Last of Us got ported to PC, they magically stopped being incredible feats of dev engineering and best games and suddenly became plain?
A multiplatform game is only made for maximum profit.
An exclusive game can also be made to be a high quality showcase for the brand. (like huge budget single player games with no MTX)
Different development circumstances that can lead to different results. Porting a game later to rake in some extra cash has nothing to do with that.
