The "quality" Apple delivers is by now a complete joke. It's going south since over a decade, and this never stopped.

It's like that because people are still buying. Even for the ridiculous prices Apple asks for.

So why would Apple actually care? They get away with this "quality", so from a business standpoint there is simply nothing that needs investments or even just attention.

It's a race to the bottom. Like everywhere else. That's simply how the system which people created works.
