Would you feel the same if your phone permanently bricked itself because the vendor decided it was out of date and they just don't feel like supporting it anymore?
If you sell a product for money, you don't have the right to take that product away and keep the money.
And yes, I think it should be legal for a hardware product (like Spotify's "Car Thing" https://en.wikipedia.org/wiki/Car_Thing) to stop working because they don't want to support the online component. It's fine to get mad at the company, but I think it should be legal to do.
And Apple will no longer sell you a phone, but a license to use it. And it will brick itself when they decide (or when you try to open/repair it).
I don't think that's a reasonable reading of what it means to "buy a game", by most people's interpretation of the word "buy".
Regardless of that, the neat thing about regulation is that we don't have to settle for that interpretation, and instead force the one that's better for the consumer!
