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.
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.
