That’s true, but I remember rumors at the time that Onavo already supplied analytics to FB at the time of instagram purchase.

Google gave me a paywalled link to FTCWatch that supposedly has the details, but I can’t check.

Yes, they did supply data to FB (under the same contracts as everyone else). However, it was only supplied to the sales org, not the product org.

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.
