I guess it is some kind of "gotcha", intended to undermine "woke" people but it seems a bit self-defeating.
"White people are so racist they're even racist when they're trying to be non-racist" seems more woke than anti-woke to me, but that doesn't seem to be the intention.
Is there injustice in the world? Clearly. Are these people insufferable? Also very much yes.
In the tech context specifically, we are very international in a way that doesn't map to US culture wars, which makes the white woke people look even more out of touch with reality.
And since the negative discourse (e.g. saying "Women face so many issue in the workplace" as a man) is way more socially palatable than a positive one (saying "Women have it OK now in the workplace" as a man), people who try to be sensible about thing not directly concerning them tend to overdo it by amplifying the "everything is bad" angle.
Which is why at the height of the BLM movements, lots of well-meaning (but IMO severely misguided) people felt that 'master' or 'blacklist' were carriers of oppression, while not thinking twice about words such as 'white noise' or 'white-label' (Implying that a lack of creativity or panache is associated with whiteness, the horror!), The former was among white 'wokes' sensibility-by-proxy, while for the latter the same crowd had the experience and tool to know this argument is bonker, and that anyone having issue with the expression 'white noise' has mental issue.
I came to this conclusion after a gay/muslim friend of mine, who likes to do humoristic quizzes on Instagram did one for the Ramadan. He asked "Apart from Ramadan, what are the other 4 pillars of Islam", and accepted the Ru Paul reference "Creativity, Uniqueness, Nerves and Talent" as the answer. The only people taking issue with that were non-muslim white french dudes who felt it was islamophobic, which greatly annoyed my friend, who felt it feed into the stereotypes of "angry muslim".
