Unrelated?...you haven't been on the up and up with how things are being done by funding groups. NED has funded the April 8th group in 2008 that sponsored the whole "Arab Spring". It's given sites and sources and links. You haven't given anything to back your claim of "Unrelated and Specious reporting".
No, I know exactly how it works: The US funds what benefits them and what they believe would actually work. Yes, there was funding for some of those Arab Spring groups. AFTER it actually got started, and certainly not when military forces in those countries cracked down on them. There was precious little media on that outside of sources like Democracy Now! and Al Jazeera.
As for this article, again circumstantial and specious evidence. Other than links to his own articles, his evidence consists of the fact that they used a church for the setting of their protests, which makes them bigots and blasphemers, rather than protesting against a major segment of Putin's power bloc, the fact that Alexei Navalny would testify for them, which means that they are tied to the State Department through the fact that he's a Yale World Fellow and is involved with the Democratic Alternative. No link to the band itself, just a public supporter. Finally, there's the point that he makes that the head of Finland's p*ssy Riot support campaign is also affiliated with the Russian-Chechen Friendship Society (allegedly tying them, again, to the NED), which in his mind is a terrorist group just because United Russia said it was. Even though the articles that got them that designation were calls for peaceful resolution to the Chechen War.
So...no actual connections to the band itself. Nothing showing that they've been American-funded in any way, or that they even operated outside of Russia.
Circumstantial and specious evidence using a history of actual happenings to prop up phantoms. Nothing of his "evidence" links directly to the band in any way.
