So what are you suggesting? For Facebook to decide to just turn off the lights one day? There is evidently market for a social network like Facebook so I’m sure another would step in before too long with the same problem.
FB doesn’t need to shut down, they just need to give a fuck about the safety of their users and the societies in which they live.
It’s been evident to anyone who cares to look that this has not been the case.
