From Alex Health in The Information:

In a big shift, Facebook plans to signal its control of Instagram and WhatsApp by adding its name to both apps, according to three people familiar with the matter. The social network will rebrand the apps to “Instagram from Facebook” and “WhatsApp from Facebook,” the people said.

This is bound to end badly for Facebook. I can think of no one who thinks Facebook is a strong brand, let alone stronger than Instagram or WhatsApp.
