I think idea that this blog post is conveying is overrated. People said the same thing about Microsoft under Ballmer. Then he left. Nadella came in and continued many of the things that he did, and their stock price has soared. For Apple the opposite happened - their profits and stock price have soared, yet Tim Cook can't catch a break. Every little error leads to a chorus of "It wouldn't have been like this if Steve was around". Perception isn't everything.
In my humble opinion, Sundar Pichai must go. Ballmer said it best - "I am a pattern"[0]. I think Pichai has been a great manager but he, from the outside, doesn't seem to be a great leader. If he steps down, the new person gets leeway to change some things and get some social capital.
