I don't see what the big deal is, It's not like its an Epic Game Store exclusive. That would be bullshit because you have to install a different launcher on the hardware you already own.
You can buy the PS4 version of the game everywhere which comes with additional content because of vastly superior hardware. Makes scene to place this mode of game play behind a hardware specific paywall.
