But there has to be some statue of limitations here.
If a product that most probably most people use for 4-8 years develops a problem 9 years later, then as long as it wasn't an intentional defect, I think you just have to chalk that up to bad luck.
I mean, what would the compensation even be? In theory, it would be capped at the resale value of a 9-year-old MacBook. Which is essentially nothing. Apple products hold their resale value far better than other electronics brands, but that's really talking about devices 2-5 years old.
At some point you just have to say you got your money's worth out of the product in the time you used it. Nothing lasts forever, and in laptop terms, 9 years is pretty close to forever.
(Obviously it depends on the product category -- things like washing machines are meant to last far longer, and come with things like 10 year guarantees on their motors.)
