this is just racism
I spent eight years at Google, starting long before these DEI mandates came in (and did over a hundred interviews during that period). I think the person you're responding to is being sensationalist, but I also feel the way these measures were rolled out did end up missing out on a lot of great hires due to them not fitting the perceived makeup of the company.
Funnily enough, I recall a specific meeting where they were planning to roll out measures to equalize pay between male and females. Prior to the rollout, they did an internal audit to understand the extent of the problem, and the audit came back highly favoring females over males. To Google's credit, they didn't move forward with it.
