To be fair, buying Instagram so early + WhatsApp were great moves too.
Google gave me a paywalled link to FTCWatch that supposedly has the details, but I can’t check.
FB acquired IG because it was blowing up in SF and MZ (other leaders too) were looking at how quickly it appeared to be growing and how good it was.
Insta was a huge hit for sure but since then Meta Capital allocation has been a disaster including a lot of badly timed buybacks
