You guys go through these mental gymnastics instead of stating the obvious.
Minecraft is an old game that was released years ago.
If Sony decided to make Destiny 3 exclusive, they wouldn't magically stop people from playing Destiny 2 on Xbox.
Don't even know why you would even consider bringing this up.
And yet all Minecraft spin-offs that are NOT old games still go to PlayStation. Minecraft Legends in 2020 and the upcoming Minecraft spinoff in 2023 are all multiplatform.
Not to mention MS greenlighting Ori for Switch and not stopping the Switch release of Hellblade one year after acquiring Ninja Theory.
