i'm fairly new to steemit and found your post interesting and educational. If there is one thing i'd add, it is that facebook, twitter etc social media will experience a huge backlash because of the blatant censorship they're already involved in Germany with the new law against 'hate' speech. The lady who runs facebook (Sheryl Sandberg) is already on record that FB will have 20,000 people deleting posts by the end of 2018. This will not stand in my view. Apart from pedophilia, all censorship is political and destroys freedom. FB is going down the wrong track and will pay for it in the market place.
