The list is not the issue here.
In an ideal world, the list would be seen as an innocent inside joke, and be totally not newsworthy. But millenials (not all: some, enough to change the culture around this) don't know how to take a joke. Like the children of hippies turned yuppies, Gen X successors turned prudes.
If you have a name like Jonathan Lovesturds, sorry, but the name is funny, and you should be expect people to ocassionally make fun about it, including in companies you deal with. It is what it is, and it's not the end of the world, nor some huge abuse (my surname had pun potential, so I got some of this as a kid, big effin' deal).
The "politics at work" thing would be relevant and legit if it was for e.g. unionizing, abuse of power from some higher up, the company doing shady business (e.g. Google and military deals, Facebook etc.) etc.
But in 2021 this more often than not degenerates in people making a power-play, abusing identity politics and other fashionable talking points, to increase their influence in the company, attack others they don't like, and so on.
Pretending the list was about "racism" (when it had absolutely nothing to do with that, aside from: "also contains a small percentage of foreign names that sound funny on top of the anglosaxon such") is also in this very vein.
