Marks on glass are not due to abrasion, they appear because glass is slightly soluble in alkaline water, which is the case in dishwashers. Porcelain and stainless steel do not get scratched by dishwashers for example.
No but the process that strips the paint off delicate crockery is self-evidently abrasive, which stands to reason when you look at the scratch marks in glass that has been through too many cycles.
It's not on glass because an individual washing won't destroy it but repeated washing eventually scratches the glassware to hell. I've seen it with my own eyes.
