The trouble largely came up because WotC didn't want to commit to calling it something because a new edition poisons current book sales. They said it had a working title, OneD&D, but then they said it wouldn't have a new name because it's the same ruleset- but the designers kept calling it "the revised edition" on interviews.. but the only official thing to differentiate the rulebooks as per DnDBeyond is DnD5e2014 core books vs DnD5e2024 core books.
I think people are just not agreeing on what defines an edition... which seems like something arbitrary for the creator/publisher to set. Which, in that case, it is not. But we went on for far too long without that info, so there is discourse about it.
