I understand that the 1K+ engineer number comes from Facebook as a whole, when mentioning the use of Hack as a typed PHP.

More like to give a perspective on the transition on how to come from a small company into a huge one.

WhatApps got audio and video calls after the Facebook acquisition.

Usage increased by a few orders of magnitude too.
