I think it may be a case where the last CEO or manager attempted to "diversify" the company by adding a branch and "restructuring" and now, with a new CEO without that "diversity" goal, and that branch failing there are a lot of "diverse" people leaving. As well, the article may have been saying that the company is stressful because they are dealing with reddit, and the article claims that reddit as a site is racist/sexist and that the admins trying to prevent it are getting backlash that is making them leave. And/or that this is a problem generally in tech. I don't think anyone was claiming, or trying to claim that women or minorities leave at a higher rate due to not being able to deal with stress. And if they are making that claim they are either incorrect, or those people incapable of dealing with stress should just not be working those jobs rather than trying to change them to make their lives easier at the harm of everyone else.
