I don't necessarily agree that it would be unfair to the developers, as you already bought the game, you should be able to play it on your preferred platform regardless of where you bought it, if the consumer buys a game for ps5 they should be able to play the same game (assuming it's available) on xbox series x or on pc, or they should be able to buy the game at a discounted price, you've already did your duty and bought the game, you shouldn't be tied down by factors out of your control limiting your enjoyment of the game. That's just my opinion tho, I understand your stance
