I think this is a great move. My understanding is that some reporting chains in facebook have 12 links between IC and Zuckerberg, which is crazy inefficient. Enormous organizations are able to run effectively with 5-6 links from IC to CEO. Managers managing managers managing turtles all the way down is a horrible form of "administrative bloat". You see bloat like this in enormous organizations like colleges, governments, and now monopolistic tech companies. This is besides the point that I don't think that big tech has successfully groomed many managers into people are capable of actually managing businesses; they don't drive value, they preside over decisions and make a case for higher headcount in the next planning cycle.
