I'm not certain about this but personally I don't think this is the intent.
I see two big benefits of these big language changes:
1. Much of anti-black racism in history has been accompanied by associations of skin colour to other unrelated elements based on their "illumination". Negative associations have been highlighted by virtue of the darkness and unilluminated things in general being traditionally considered negative.
So the original meaning or intent of blacklist/whitelist doesn't need to have been race-related for it to reinforce the idea of black=negative & white=positive. This is an association that's as natural as kids being afraid of the dark, but an association that is helpful for us to subvert and overcome as adults (for a plethora of reasons, one of those being to do with race)
Having discussions about language and naming things helps with that subversion.
2. In my case, as I work for a company that is bringing in these name changes internally, I've found this a curious and positive rare opportunity to discuss & hear team members' views on this issue. It's not the type of topic that would normally be easy to bring up in a corporate environment and this makes it natural and "safe" to do so in a not-combative way.
