Whitelist/blacklist have their origins in terms from the 1400s and nothing to do with race (they have to do with criminality). Twisting their etymology to fit some kind of racial bias is sort of weird.
And throwing aside 600 years of clarity for "basic manners" also seems rather weird. Sort of like banning the word "engender" because a small minority might find that to be offensive. It isn't clearer to use a different word than has been used for over half a millennium.
For a while, people were getting in trouble for using the word, "niggardly," even though it had nothing to do with the offensive term that it sounds like.
The difference being that the controversy around white/blacklist only appeared after someone said it was a controversy in 2018, which is extremely recent, and the wording doesn't contain any phonetic similarity to a term from slavery. Being able to be misheard is more of a problem when phonetics clash.
Should all terms for the colour-that-is-somewhat-the-absence-of-colour now be banned? Is Vanta Black now racist?
Manufactured controversy leads you down a path of absurdism. It isn't helpful to the people it purports to help, whilst granting the vocal group the ability to say they're being helpful whilst actively ignoring any actual problems.
Blacklist/whitelist are not used consistently, so the clarity is not there. You can't see whitelist and consistently know whether it's going to be an allow list or a deny list
I don't believe I have ever seen a single example of a whitelist not being a list of exemptions. Nor can I seem to find any.
Nor can I find any example where blacklist is not a list of denied subjects. A blacklisted person, website or process is immediately clear within their context.
Where the clarity is lacking is not clear to me. However the mismatch between "allow list" and "whitelist", is. The latter seems to have a different meaning altogether.
