Earlier quoted context omitted.
I'm not seeing any connection between the linked discussions and identity politics, and I'm certainly not seeing any connection with Brendan Eich. Hopefully not every thread that involves reference to a CoC has to automatically turn in to a grievance bin for people who have a bone to pick with identity politics.
The second link in this thread ( https://news.ycombinator.com/item?id=28515306 ) includes multiple alleged statements that are about identity politics. One example being: "saying incredibly horrible sexist and racist things such as 'kill all men', and actively trying to prevent white men from speaking at tech conferences" Which seems to be connected to identity politics.
E.g. with respect to the wasm-pack both sides have reasonable arguments in the thread how I read it.
With respect to unsubstantiated accusation, that very post makes accusations of nepotism without any proof.
