Not to mention more descriptive. If you hear the term "allowlist" or "denylist" it is immediately obvious and self-explanatory, with no prior context needed.
Leaving aside any other reasons, they're just better names.
No yes no.
As for the post you replied to, allow/deny are indeed the more descriptive terms for lists that allow/deny access. Descriptive terms are good and useful.
