Why are the cans always upside-down inside a case of Coors?
They aren’t upside down…you are! 
To clarify…the six pack plastic rings are affixed to the bottom of the cans…not the top.
It’s senior friendly? Or worse, child friendly.
Dude, where are you? Around here (California) Coors has always been packaged in cardboard carriers for the cans, not plastic rings.
Slight hijack;
Do some soft drink brands sell “9 packs”… where there is an additional row of 3 rings, to form a square?
