Facebook has added new tools to allow prevention of sharing of websites that are not approved of; at least that is claimed at https://www.zerohedge.com/news/2016-12-15/facebook-rolls-out-tools-curb-fake-news. The stated intention is to block out fake news which may mislead innocent readers. However such tools can, and I am sure will, be used to censor sites that try to tell the truth that ‘white listed’ mainstream sources avoid telling.
But is the zero hedge article itself a lie? One clue is that when on 15 Dec 2016 I tried to share it on Facebook I was told it was not trusted and when I tried again I got in such a tangle that I had to get out of Facebook. So at least some of the tools that zero hedge allege exist, do in fact exist.
If zero hedge article is true, it seems that Facebook itself will no longer be trusted for the dissemination of genuine news.
