Is it possible a rogue terminal sent a strange or too strong signal to the card during use to zap it? Seems like some call it detuning.

I don't think that's likely. Per the article, detuning happens with UHF tags (which contactless cards and Apple/Google Pay aren't). I'm thinking it's something related to getting one of the first cards and the bugs that result.
