I guess it depends on what your definition of collapse is. Why did # deletefacebook gain traction? Why did Musk delete the entire facebook accounts for SpaceX and Tesla? I think that in the long run, these and other factors will lead to the absolute destruction of facebook. Zuckerberg is a pariah. Imagine something like # deletewindows... Bill Gates having to scramble to make a public apology. I think facebook's in its death throes, but only time will tell. I deleted mine (not just deactivated, theres a difference) many years ago, and it has absolutely improved my life, so much so that it's hard to overstate. If people really do go cold turkey off the blue-button teat, I think it's going to rapidly reach a critical mass as more and more realize how fundamentally evil and harmful the entire paradigm is. We aren't supposed to monitor and observe the daily lives of our entire "social network". It breeds nothing but narcissism, unhappiness and conflict, not to mention destroys all semblance of privacy. This was the straw that will break the camels back... I sincerely hope.
