Hello aruzinsky
I read the similar question in the Linguistic forum. I didn't trace your discussion to the end and I have no idea about the meaning of bare plurals.
I just came across the site in which three key words: AI, the interpreation of expressions and the legal responsibility. I refer you to this site, although there's no mention of bare plurals. Hope it concerns your question even if slightly.
