Many applications of glass have coating that do scratch easily.

I use high index Nikon glass for my glasses, my iPod uses some sort of borosilicate glass, IIRC, and my phone uses Gorilla Glass. The Nikon has an anti reflective and hydrophobic coating which means it needs soap and water to remove oils. The coating for Gorilla Gass is not oleophobic by any stretch of the imagination, and regular window glass needs microfiber or similar cloth to remove oils completely as you're just otherwise smearing it around instead of leaving it all in one discrete spot.
Most glass used outside of food serving purposes seems to be coated with one thing or another, especially in electronics for screens. It does not clean with just a simple rag - I have looked at them under good light and see greasy streaks, although they don't mess up the image unless there's sunlight or similarly bright illumination to get reflected from it.
That's why I use screen protectors which have oleophobic properties... as even the iPad isn't very oleophobic, no matter what Apple says about that. The reason they're so shiny in Apple Stores is because there's an associate with a microfiber cloth and spray cleaner wiping them down every fifteen minutes. I've watched.
