Household dishwashers are not affected because they usually have an additional wash cycle in the end. This study is about professional machines which wash dishes in mere minutes. So you can't do anything about it if you still want to eat at restaurants and don't want to bring your own dishes.

Always wondered what dishes look like with rinse aid and why people buy it. What am I missing? Are my dishes and glasses not sparkly enough without this aid?

[instagib]

Hard water. The rinse aid fixes that. Otherwise my glasses or silverware have to be rewashed and dried to get the spots out.

Are you using tablets?

[TedDoesntTalk]

No - liquid. Why? Does it matter?

[dellamorta]

Tablets have rinse aid already added. I don't know anything about liquids, though. It is not a thing in Germany afaik.
