Interesting, but the title doesn't really match the contents. It sounds like it'd be about sexism/ageism/racism in the tech world, but it's more just a summary of fairly interesting facts about this group of elite tech companies. Still a good read, but the article itself is less controversial than it sounds.
Looks like a case of blogspam linkbait. The original TC article has a lot more interesting details, and it doesn't even mention race in the entire article, much less with a sensationalist headline, which in this case seems to be extrapolated from a much vaguer and less controversial quote in the article.
I'm flagging this article, but I'd upvote the original TC one.
