I don't use Facebook, but over the last several years I kept hearing from a number of non-PC type news outlets (that I subscribe to) that even as their media platform grew and doubled and tripled, at the same time their Facebook engagement became a small fraction of what it used to be.
I've also heard that one of the quickest ways to get your Facebook account terminated in Germany is to say anything negative about the current migration situation that becomes popular or starts to get views.
This article IMO is a way to hide the real story with another story.
