I actually think reddit has fallen in to the opposite trap here. Because of the increased scrutiny that people of colour get when being put in these roles we see this trend that only massively over-qualified PoC are being put in these roles. As a result you end up in a situation where you aim for an increase in diversity but in reality you end up with a handful of people who are rotated through all the possible positions. Simply because everyone wants the signalling of hiring diverse people, but no one wants to take risks when doing that.
