You seem to be talking about Facebook the company, whereas the parent comment is talking about the social media platform. I'm not sure this rebuttal is relevant since the original claim is that the flight of users is a leading indicator of the platform's demise. Facebook owns Instagram, so maybe it's ad revenues are coming from places other than facebook.com?
