That's exactly the justification the Chinese government uses.

“Today we have fake sites, bots, trolls — things that regenerate themselves, reinforcing opinions with certain algorithms and we have to learn to deal with them.”
Merkel, 62, said the challenge for democrats was to “reach and inspire people — we must confront this phenomenon and if necessary, regulate it.”
She said she supported initiatives by her right-left coalition government to crack down on “hate speech” on social media in the face of what she said were “concerns about the stability of our familiar order”.

I might sound like I'm being a bit hyperbolic, but I find it deeply scary that Facebook is applying its considerable engineering talent towards building censorship and monitoring at scale. Facebook has some of the smartest engineers in the industry as well computing power that only the richest governments can match, and they have a good shot at cracking the problem of doing efficient censorship at scale. China manages to scale its censorship by employing more and more people to censor. If Facebook builds a plug-in system that allows governments to censor automatically, then every country could censor like China, at a fraction of the cost.
By implementing censorship FB will make such option even less likely to happen in future.
It’s a step down a slippery slope toward worldwide total surveillance and censorship.
These tools can and will be used against activists, members of minority political parties, dissidents, business rivals, etc.
When some African dictatorship jails some journalist’s whole family without charges, the engineers at Facebook who built the surveillance software will be complicit.
