The fact they went with "Perhaps your undereducated", while still being dumb about it.
If steam itself has already during 2024 made it clear that their clients will not support those versions, then they wont be supported no matter how much you wanna pour your heart and soul that you bought the game, knowing already its not going to get windows 7 supported, and still want to complain over their own ignoreance.
The game was released on steam at 22 June, 2024.
