The kind of nonsense described in this story is exactly what I'd expect from an early stage software startup back in the early '00s, when I was first getting started (not in SV, mind). It was common to mock people and create memes for any reason (the Basecamp "foreign sounding name" kerfuffle very much reminds me of this).
This kind of culture was unacceptable back then, of course, but the founders and owners were little more than children themselves. It was at least understandable if not excusable.
What completely boggles my mind is that, some 20 years later, this kind of culture is still happening. And it's not happening at some small tech startup founded and run by young men barely out of school - it's happening at a wildly successful car company which has been around for over a decade run by the richest man in the world.
The culture at Tesla must be rotten to the very core for this to persist so long.
