Well I hear that you can ringfence your own Facebook activities. But knowing what I know about the harm that can be done to vulnerable people, the lack of control over children using the site, the trolling and hate speech that often goes untouched and the various incitements to violence, self-harm and suicide, etc. etc., it's a line that I personally won't cross. That's just me and for all the reasons I mentioned before I can't criticise those who come to a different decision. To do that would be hypocritical. The company that owns Facebook, etc., makes billions a year in profits. I might think differently if some of that money was used to employ armies of moderators who would pre-moderate every post that was intended for the public domain and close the accounts of people who continually violate the rules. Yes I know there are issues with that. Far too much profit, far too little control going on. No Wild West for me, thanks, and no unintended support for it either.
