Question: does it make sense to block games from getting to sony's platform?
In an emotional console war, sure it does. But in the name of profit? no. They want players considering buying a playstation to know that Doom, or The Elder Scrolls, or FIFA, or Madden, are $70 there. But that their console comes with two years of free access to those games, plus hundreds of others. That is quite compelling.
Failing to convince players to get an xbox and sign up, their next hope is to get you, the guy who was gonna buy on steam, or playstation, to get your Fallout at a fraction of the cost, through game streaming or game pass for PC. Can they get millions of laptops, smartphones, etc, buying an xbox controller and paying for gamepass? They want their games to be big, youtube successes like Animal Crossing was for Nintendo, and they want to profit by always positioning themselves as the best and cheapest way to play the game.
