You're right, they don't… initially. And Apple is clearly relying on that for their "Sucker's Buy" entry-level system spec'ing and pricing.
However… customers don't usually stay ignorant for long. They eventually start to complain about performance, "Why is my computer slow?" And when they, inevitably, hear the answer, "Because Apple shortchanged you on the components they put in that model", they almost always—right then and there—decide to never buy a Mac again. They'll go back to the Windows world… where they expect that kind of nonsense.
This is why this Exec Team's short-sighted greed will eventually befall it. Thing is, this exact thing happened to Apple before; it has been warned about, repeatedly… but none of these idiots were at Apple then, so they're doomed to repeat it. Sure, more money involved, the size of the company bigger, yes, yes… but all mighty eventually fall. All.
And this was 100% avoidable if Apple would have just stuck to it's "first principles", as Elon constantly preaches: if Apple would just deliver the best devices for value (a price that is commensurate, which can be higher than competition) and back that up with customer service and support that matches their PR narrative, they'd not be facing this. Instead, they chose massive stock options, gaslighting consumers with propaganda, and "luxury" faux-quality. It's made them rich; but the community is now poorer, and it is finally starting to really show.
