You were downvoted, and while I think DEI has some good aspects, your 2nd point is spot on because I've seen it in person at a largish, household name tech company. You see Indian managers who only have Indian engineers working for them and you see Chinese managers who only have Chinese engineers working for them. Go through the cafeteria at lunchtime and you see it pretty much ethnically sorted - the Indians aren't sitting with the Chinese, and vice versa. Now it wasn't 100%, I worked for a guy who was ethnically Chinese from Malaysia and he had Indians and whities like me working for him. But if I saw in internal job listing that looked interesting and the manager was Indian, for example, I'd look at the org chart to see the names of the people working for them to see if it was an all-Indian group. If it was then there wasn't much point in applying.
