100% agree on Zuckerberg really understanding Facebook and where it needed to go.
The most interesting part of the email to me was seeing his support for aquiring Unity. Not being able to land that acquisition almost feels like the critical reason Meta doesn't have much to show today, after all this effort. And it doesn't look like the aquisition failed due to lack of trying! ironSource ended up doing a merger acqusition that finally closed just a few days ago.
