By my reading, the outrage is likely coming from the cushioned stereotyping from the podcast participant. They're stating that "neckbeard types" and autists aren't customer-ready and are uncomfortable talking with customers. That second part is worse because it may lead to assuming that those folks would never want to talk to customers, or even learn how, and so the PMs might "protect" them by never offering them the chance, while assuring themselves "that's okay, that's great, I mean it takes all kinds".
