They gave up on permanent exclusivity a while ago, this isn't the first game they've let slip to Playstation. The rule of thumb is now that MS games launch on both Xbox and PC then go to Playstation after a year or so, Sony games only launch on Playstation then go to PC after a year or so, but never Xbox, and Nintendo exclusives are still forever aside from some weird China-only deals.

Actually, Helldivers 2 was brought to Xbox 1.5 years after the PS5 / Windows release. But that's a live service game, so more players = a better experience.
XBOX has outlived its usefulness now that all the anti-General-Purpose-Computing “““Security””” bullshit has metastasized fully-formed over to regular PCs after incubating for twenty years in console-land. They knew people would protest that stuff if they tried to develop it natively on PC, but nobody bats an eye when they lock down some appliance machine whose exclusive software “needs” to be protected.
