who blows 6 times the cost of an in cabin airfilter, to have the dealership replace it? That's just wasting 60 bucks for 30 seconds of moving your arms, and opening your glove box

80 bucks for the dealership to swap out the filter that is behind the glove box. That's all there is to it, and the filters cost about 15 bucks:

the way I figure it, pointing out the rip off stuff like this, is one good reason to have a blog. 

And I never see real world applications of using a car enthusiast magazine for something as real as this. 

Why do dealerships charge 80 bucks to do replace the cabin air filter? 

Probably because the dealership service center is basically the money maker department.
