 of terminological drift) that "I'm in no position to legislate usage." Hence I make this appeal. Whether you think "gold OA" means "journal-provided OA, regardless of business model" or "journal-provided OA based on author-side fees or APCs", you could still communicate more effectively if you'd use clarifying adjectives to modify the noun, for example, "fee-based gold" and "no-fee gold". If it's important to refer to APCs, then "APC-based gold" and "no-APC gold" would also work, although they will be less self-explanatory to outsiders.
