I think it’s because the word “anonymous” permeates our understanding of the concept, and – even for people who didn’t actually study Greek – the tie to “name” is clear. We need to understand that “knowing someone’s identity” is not coextensive with “knowing their name”, and that in fact knowing someone has a rare medical condition may be more identifying[0] than knowing their name. [0] Or k-deanonymising, for anyone who’s pedantic about identity being an absolute.
