I think their point is that there was never any reason to even know what people identify as, or your political views, and that there still shouldn't be. That things like "diversity" in online-only circles doesn't really make sense. I don't want to know your sexual preferences or your gender identity, not that I am against anything, just that it's completely irrelevant to writing code and learning about technology etc. and only seems to lead to more drama by including it at all.
As a more personal example, I no longer support the Linux kernel because I no longer consider it fully "open" to contributions, especially when accepting those contributions are no longer based solely on technical merit, but are also actively rejected for political reasons, even for patches that are merely fixes, which benefits everyone, and not just a sanctioned country. Even going so far as removing names from the maintainers list because of some unspoken combination of their country of origin, employer or political affiliation. Not only the lack of advance notice, transparency and empathy, but the abusive attitude Linus continues to display to the world about this and many other issues.
