Whitelisting and greylisting is still fine. The current movement (primarily in the USA, but not only) to replace the word black where the meaning is associated with something negative is quite superficial and happy with simple swaps. And this fine because if we went deeper, we would have many problems related to the fact that many positive values are associated with light and many negative with darkness. So people would either have to rewrite the fundamentals of our culture (and maybe even biology), or to accept the fact that these two - the pigments in our skin, which is neither white nor black btw, and the culturally-influenced meanings of various colors - belong to two different semantic planes.

Can't say of grey list but white list has been renamed to allow list in a few places i know

allowlist has been suggested for whitelist.
