As long as it’s legal, they shouldn’t be policing transactions at all!

Well, they aren’t policing transactions per se, they are a lot more Machiavellian than that. If they were policing transactions, it would be much easier to fight.

Nintendo is doing exactly that (pulling games from stores, letting them die). Now that they have more invasive DRM in their latest console, they might even take a more active approach like Ubisoft wegen it comes to live service games. Let’s just “sunset” Mario kart world live service and brick it in a couple of years?
