Using cost of switching as an alternative would seemingly have ramifications that could be applied to almost everything from Fortnite skins to membership stores to video game consoles to state governments.
You could always try and find out! Your freedom to take digital purchases (and save data) between different console platforms is a factor here, and historically some platform holders have actively prohibited it and others have not.
Only recently did Destiny 2 gain the ability to transfer save data between platforms. Oddly enough Epic pushed on this kind of freedom too: They wanted PS4 and XBox players to be able to play together, but Sony kept resisting it. They eventually pushed hard on it in public and got concessions so everyone can play the game together now. Now other multiplayer titles from smaller studios also can offer cross-play.
Platform exclusives like a spider-man outfit or playable character are still typically locked to your PlayStation, though.
