Let's just say that the "sour grapes" crowd are much more likely to pile on to stories like this.
Facebook provides me and my friends with immense value, I'm a very happy user, and as long as that value is higher than the annoyances of using Facebook, we will keep using it.
The reality is that Facebook's DAU numbers and engagement metrics just keep on rising. A bunch of disillusioned users on this forum is not a negative trend. Facebook's biggest enemy is themselves, because the corporate machine pressures everyone there into change for change's sake, which fuels user fatigue, which in the end will lead to some sort of exodus.
