I've worked 10+ years in Silicon Valley and the motto "it is better to beg forgiveness than ask for permission" really does ring true. This manifests at all levels from ICs and up the chain of leadership. People do what gets them their bonus/promotion and everything else be damned. "Acquire the customer and fix the security problem later" was the mindset here.
