Sure I get the silence but there was no need to blame the US media in the first place. Silence in the first place would have been fine for the Kremlin.
Given that people here are apparently specifically looking at Ed's words, maybe it wouldn't though. The first thing to die in war is the truth, I've heard said. The Russians need all the good publicity they can get, every bit they can reduce blame or normalize the actions is going to result in lesser sanctions. Ed might have been politely asked and realized it was not a question or suggestion; we don't know.
Considering that he's sheltering in Russia right now I would strongly suspect he's going to keep his mouth shut no matter what his opinion is about it. If Putin kicks him out he will be extradited and thrown in a US federal prison solitary confinement cell indefinitely while 'awaiting trial'.
Maybe he only now realized he's just an asset. (As opposed to Assange in the Equatorial embassy, which was given asylum for purely humanitarian reasons)
He retweeted Suchkov's summary of Putin's "address to the nation regarding his decision on Donbass" (https://twitter.com/m_suchkov/status/1495831112102338563). No surprises there about where Snowden's loyalty currently lies.
