Thanks for your comment. We follow AP style (mostly) at TechTarget. My recollection is that I found a reference to that being AP style for abbreviations ending in “s” but I’m not entirely sure.

I’ll continue to look into this one, but for the moment, I’m sticking with my “treat it as a word” justification.

CMS and CSE go on to explain when an apostrophe might be used to pluralize an abbreviation such as PhD. But there doesn’t seem to be any documentation at all for “b.”
