You may genuinely not know the gender of an online nickname, and, frankly, you also don't really have to know? Why share this metadata in the first place.
I kinda see your point regarding "it pulls in culture war", but, to be fair, it's "they/them". Language that - in this very usage - predates the culture war by centuries.
So.. idk I think you might be wrong here.
"There is an entity named doob, and they are responsible for this thing" at least to me kinda solves the exact thing (attribution, "where to ask questions") it needs to solve, while simultaneously encoding the least amount of metadata possible.
(Okay technically the entity is named mrdoob as an opaque string, but "there is an entity named doob" was more fun to type)
Haha what the fuck. Who implemented that oh my god.
Genuine question though. That cannot be grassroots, can it? Because it completely defeats the purpose of that. Did this just come up because someone _had_ to translate the english culture war during news reporting?
