Beat me to it. I was gonna say "I made a part for Curiosity Mars rover. I'm a flippin' astronaut!"
Having worked lived in a coffee house that started with green coffee beans, then roasted them to many different levels on site, I know that oils are used to cover use of shitty coffee beans.
When you make coffee from good beans that aren't slathered with "flavor oils," you don't have a mini-slick floating on top of your coffee. You won't need sugar and won't want cream or creamer.
Millions of hard working 'Murican farmers disagree. Not to mention, most of the world just throws the ground beans into the pot of water and boils it until the water is brown.
Both sets of my grand parents got (or received as gifts) Mr. Coffees at some point. And in both houses, it sat in a corner gathering dust, while the percolators worked furiously away (stove top on the farm, a fancy electric model in the city).
Like many, many modern amenities, Mr. Coffee-style coffee makers are more interested in the continued sales of unnecessary disposable filters.
