I think Ben got a bit carried away but it does not do to over-inflate what the papers reported which was already over inflated from what he said. There is a massive difference between influencing a result and fixing it. Of course cyber hacking to fix a paper count is daft. But he didn't claim it. He was talking about fake news articles on Facebook etc and how they could influence things. Of course the vast majority of fake news was generated by the campaigns themselves but there was also some articles by enthusiastic citizens on both sides on Facebook, some accurate, some wildly inaccurate. That Russia produced any of these for Brexit is a suggestion too far without evidence, in my opinion. But that fake news is a problem and that many people including Russia produce it is, I think, accurate enough.
