For instance, I bought Super Mario World for the Super Nintendo Entertainment System. That game is locked in. No fixes, no additions, no nothing. What is on the cart is what you get. Nintendo has no more obligation to me and I have no more obligation to them.
But people expect updates and changes. Let's not talk about "incomplete games being finished through updates", games get updated all the time now. Even for physical copies. Games now often install on the hardware and check for updates on first run.
So if we go to "buy", if you get a broken game, that's on you. Don't buy from them anymore. You don't get to hound the developers to "fix" the game. You paid for the thing, they gave you the thing. If you want a refund, return the thing.
I think we still haven't quite figured out how to work with ephemeral goods like software. It's kind of like a performance, kind of like a physical item, etc. It requires far more effort to generate than it does to copy. And buyers want to buy on the value of the copying, but sellers want to sell on the value of generation.
