jq, I was about to get a used Switch in trade for some other electronics I'm selling, so I quickly did some homework to see what the pitfalls might be and ran across this. It also made me decide not to buy that, or any, used Switch unless for a purpose where online access is completely irrelevant.
Buyers should consider consoles in 2023 as perishable, consumable goods, and probably as fit to purpose as a used kleenex.
