Maybe I missed something, but that article didn't seem too enlightening.
Isn't it common knowledge that bare copper will tarnish? 
and that silver coatings need to be protected with "silver saver" paper or some type of good packaging until used?
(a "no brainer" study, if you ask me...)

It might not be wise to store "piles of reels" in cardboard boxes for nearly a decade,
but the component termination plating on those probably aren't copper or silver.

I thought the original question was about shipping final product, not about wettability.
What is the danger of shipping AFTER SOLDERING in cardboard? 
Maybe not the cardboard, 
probably the moisture.
