It’s the one with a dev that thinks that replacing “he” by “they” is political propaganda?

Yeah, no thanks.

Can you provide some context?

Edit: I found the context. Here and here.

maybe I’m not seeing where the smoking gun is, here. I see a guy saying something akin to “can we not do this here in the github please”

and then I see a bunch of people blowing up and yelling about “dehumanization” over it.

…why is this such a huge deal exactly?

Absolutely nothing. The fact that they had to bring up a totally irrelevant 3 year old issue during an event that is supposed to be celebrated tells you a lot. They have been blatantly brigading various communities just for attention, and probably to get the dev cancelled or something. Even this post, the privacy community does not need this whole chain of replies. And yet, they overshadow every legit discussion with this bullshit unprompted.

Open mindedness is a key factor for success (especially in open source). Inclusivity demonstrates open mimdedness. The fact that the lead dev goes out of his way to prevent such a minor change (it’s not even like people demanded a CoC or something) is a bad signal
