Because once the car is out of warranty, they could care less. Only time they care is when the govt makes them for a safety issue/recall. There is no money to be made by anyone by doing it, so why bother?
You also have to look at engine tolerances, newer engines are much better (not all, but most are) than the older ones, plus if you tell someone that has a vehicle that uses a qt of oil every 1000 miles they can now go 7500 miles between changes, they will run out of oil because most never check their oil anymore, they just change it. For them, a 3000 mile oil change is what they need (and deserve).
