Create social media campaigns to promote social cohesion? I'm, er, actually okay with this?
The article says "politicians’ statements, vigils and inter-faith events are also negotiated and planned in readiness for any terrorist attack". Nothing about that strikes me as particularly harmful; a government promoting social cohesion during times of turmoil is standard fare. What's upsetting about that?
Welcome to Russia.
This article is from a dubious source, and is rather light on sources. Nowhere is it alleged the UK government is abusively creative accounts on social media.
Can this be interpreted in any other way?
The third sentence further explains the false spontaneity: "In operations that contingency planners term 'controlled spontaneity', politicians’ statements, vigils and inter-faith events are also negotiated and planned in readiness for any terrorist attack."
Basically: the UK government coordinates social media campaigns to promote social cohesion in the wake of terror attacks, and additionally coordinates with community leaders and politicians. That's all you can draw from the article, unless you have additional information or sources to the contrary.
