The more interesting question I have is how he knew the speed that IG user base was growing. The threat that Google may acquire IG when IG was barely a year old seemed quite paranoid, especially when Google had almost certainly ceded its Google+ effort by then.<p>If anything, the rumors in startup land at the time had Twitter as the likely buyer and IG was quickly integrating with them. It was a product that, to this day, never felt at home with the FB News Feed. Threads is the proof that it really should have been a Twitter product.<p>Zuck does make fair points, and his direct reports calling out "team issues" seems like excuses. If anything, the "efficient" mono corporate culture of Facebook makes launching a whole new product that isn't just a feature of a bigger product almost impossible. I was on a couple zero-to-one efforts that never made it past the prototype stage because it couldn't really find a home in the bigger orgs. Camera was no different.
