Right but that coating can come off with an abrasive cloth. The oleophobic coating doesn’t last forever and between our hands, pockets, etc, it eventually wears down. Polishing the screen with an abrasive fabric (even if it doesn’t feel abrasive to you) only hastens that wear.

Holy shit is the ignorance palpable here.

I’ll bet you blew into your game cartridges as well and still have no idea that was the cause of the issues with games.
