This is a far cry from having a coordinated disinformation campaign to cause political instability in a foreign country. The evidence of Russia doing this to any effect with Trump or Brexit is extremely scant and circumstantial. Such a campaign would be massive, well beyond the capacity of a hidden conspiracy. It would involve entire media companies and NGOs. There would be far more smoking-gun evidence than the current standard of "guilt by association with someone who spent some time in Russia".
