Really very sure that wasn't one of the conditions. I didn't remember that from 2012, and looking now it wasn't included in the merger agreement. They did write:

> We believe these are different experiences that complement each other. But in order to do this well, we need to be mindful about keeping and building on Instagram’s strengths and features rather than just trying to integrate everything into Facebook.

>That’s why we’re committed to building and growing Instagram independently. Millions of people around the world love the Instagram app and the brand associated with it, and our goal is to help spread this app and brand to even more people. -- https://about.fb.com/news/2012/04/facebook-to-acquire-instag...

That looks to me like what they've done?
