A few weeks back, Instagram co-founders Kevin Systrom and Mike Kreiger announced they were leaving Facebook six years after the initial acquisition. At the time, reports suggested a growing rift between Instagram leadership and Mark Zuckerberg, and now Systrom has publicly addressed the relationship for the first time.
