Terrible decision. Playstation games should be released ONLY on Playstation.
Why is that? So you can feel like your in the special cool kids club? The industry is changing, exclusives are slowly fading away. Get used to it. This is better for gamers in the long run. A PC user who spends thousands of dollars on a high end rig deserves to play fantastic titles just just as much as a person who purchased a $500 plastic box of their choice.
It also makes sense business way, they're leaving lots of money on the table by excluding PC. I own a PC, Series X and PS5 and have 0 regrets and I love them all.
Consoles these days are more for the convenience. Instead of spending a ton of money on expensive GPUs and CPUs, you get fantastic performance out of the box. You don't have to deal with system crashes as much, weird software/hardware bugs and driver updates. This is why you buy consoles. The exclusives are part of the bonus and came with the territory, but now more people will have access to the "exclusives" Everyone wins. For the players.
