Would a Sea of Thieves switch or PS4 port be worth it and why doesn't RARE do that?

Question one: Would a port on the Nintendo Switch or PlayStation be worthwhile because you would reach more customers?

Question Two: Why did RARE, the game's developer studio, only release the game for the XBox and Microsoft?

Microsoft has taken over the developer studio, Sea of Thieves was initially only Xbox exclusives and Microsoft Store.

The game for Switch and PS would probably be worth it, but with the Exclusives you want to make sure you buy the Xbox.

Of course, a game sells more often when it is released on multiple platforms, it would also be cool if it came on the PS4 and Switch including crossplay.

Because Rare is a Microsoft developer.
