Hello there[url=https://media.giphy.com/media/rx3flR1eNqciQ/giphy.gif],[/url] Platform licenses are basically permission to play on their platform for a percentage of the sale price. The store takes their "cut" to account for selling the game and allowing it on their platform. If xbox gets their cut to allow us to play on their platform, they do not share that with Steam or Playstation to allow access to those platforms. Similar to when you buy a game disc, buying a copy of a game for PS5, that disc will not work in an Xbox.
