Mr. Lynt is mistaken in his
Mr. Lynt is mistaken in his belief that acronyms are subject to different rules than other English-language nouns. As explained here - from the web site painintheenglish.com/case/333 - that is not the case:
"You make the plural and the possessive in the usual way for acronyms. For example: I had a VCR. The VCR's power button was broken. I bought another VCR, so I had two VCRs. Then the second one's channel selector button broke, so I could tell that the VCRs' buttons were made cheaply."
In that Mr. Lynt has not taken even minimal care to avoid a preposterous, if amusing, misspelling of the word 'apostrophe' in his post ("appostrophy"), his credibility on such topics is open to expansive question.
One further point: the Nissan corporation, which invented the LEAF acronym, has explicitly advised that the plural of LEAF is LEAFS, not LEAVES. As Nissan contrived the construction originally, it seems fitting that Nissan is entitled to specify its plural form.
