On Xbox and PS5 (the closest GPU equivalents are the GeForce RTX 2070 / RX 5700 XT) the requirements for running the game are not that demanding; on a PC they feel they can do everything and people will buy...
There is ATM an excess of GPUs on the market, so maybe they have an agreement with someone to give a push to increase sales.
Most of the time I think people are safer with a present gen console where things must be optimized and there will be no "requirements ' surprises". On a PC you must spend hundreds of $/€ every two years (are thousands every 4) of you want to play Ultra settings. Hardware sales will thank you...
