From a business prospective, If your whole idea is to sell your console as often as possible it’s not a good idea to make your games work on every platform. Console exclusives are a big part of the selling strategie.
Also, as always, if you own the money you should buy a game to show support (especially if it’s an indie title). But when it’s an old game owned by a company who still thinks we are in the 90s. Which dosen’t want to sell the game to you anymore but at the same time forbids everyone from making a copy of the said game, you should absolutely pirate it.
It’s sometimes the only form of game preservation we have.
If we somehow discover a second library of Alexandria and it also turns out that infringes on a Nintendo IP, I have no doubt that Nintendo will burn it down immediately.
