The PS4 version of Minecraft was released before MS purchased Mojang though. None of the games released on PS4 and Switch, namely Minecraft Dungeons and the two Ori games are anywhere near the significance of an Elder Scrolls or Fallout in terms of a console's exclusive line up.Well the same logic would apply to Minecraft, and that's not been the case. I don't blame people for asking questions, considering how unusual MS's strategy has been in terms of exclusives hitting other systems.
The biggest MS published release on another console after the purchase of Mojang, was Minecraft on the Switch. But I'm not sure MS views Nintendo as the same kind of competition as they do with Sony.
