Unless the filter plugged up you are correct but the problem really comes in the form of oil getting past the seals and the oil not being filtered at all... Most people know nothing about anything much less a oil filter or oil.... The what evers cheapest is the key.... Most cars don't have any sort of gauge , some only a light so people don't know what or even how much pressure the car has normally.... Then you throw in high volume pumps instead of high pressure and even a shade tree mechanic is lost.... I prefer high volume btw.... I have torn down thousands of engines over the years and trust me when I say people don't know how to take care of them....Now let's talk about draining and replacing tranny and differential oils... It's never done and exactly why newer cars don't have a place to add tranny oil or even a filter you can change without cracking the tranny in half.... I worked for a short time for an auto parts store and people won't spend an extra dollar on stuff....
After buying my truck, I went hog wild on research of maintenance. I was disgruntled to find that I couldn't even CHECK the transmission fluid. Go figure, but the trucks have a good track record for this generation (2016-current). You can change the fluid in the transmission, the differentials, etc. But it just seems like you're right...the shade tree mechanic is a thing of the past.
