because of the cut in digital sales theyd get. phone companies are the current front, but its going to get extremely messy when the front gets for example, put into the console gaming front. its all for money for software they did not develop and prevent that money from going to any other payment processor.
for example on the PS5 front, sony makes more than 50% of their revenue on live service games. none that they actually own themselves. Apple, and to a lesser extent, Google, apply that for ALL software, and gain additional money from developer subscriptions. It’s the same fear Valve had back when Microsoft was pushing for the Microsoft Store to become the defacto storefront for personal computers. that push however failed miserably.
because youd only swap mobos for either aesthetics(expensive, not often done) at best because you choose to downsize, or because you need more pci-e I/O.
the average user doesn’t use all their pci-e i/o, and the ones that do, are looking towards workstation motherboards, which is almost a completely different market from the consumer level stuff. It’s a game of, you know when you need more i/o, and if you needed it, you probably would have never bought the consumer level board in the first place.
