How many people do you know with a >2 year old MBP? I would wager a substantial fraction experience this. I personally know several who get this issue wiping their screen only with water and the cleaning cloth it came with, per Apple’s instructions.
... In addition of course to all the ones experiencing this effect after using a tee shirt, tissue, paper towel, or other cloth. The guy you’re responding to definitely shouldn’t be using a paper towel to clean the screen.
Still though, that doesn’t cause a problem with most other Apple laptop/phone/tablet displays, so people who now have scratched up screens didn’t ever expect this could happen, and weren’t trying especially hard to be careful about it. Apple should at the very least do a much better job warning their customers.
