Whereas blacklist in its original forms was used outside of a racial context. I think it'll be pretty hard to try to break the association between black (the color) and night, hiddenness, unknown, sin, fear, etc. All of which are pretty negative, but not originally racial.
I find it difficult to distinguish one of these changes from the other in terms of usefulness.
I also don't hold much truck with the 'insulting' and 'patronising' thing. It's perfectly possible for a white person to prefer to remove inappropriate and confusing terminology that trivialised historical injustices and/or glorified things they disagree with regardless of whether or not non-white people are offended by such usage. There seems to be an underlying view that a white person could only want to change such usage for inauthentic reasons. If we want to find things patronising, I find that patronising. Just because you're white doesn't mean you can't hold an authentic position of your own on these topics.
