Can you provide sources for this?

The source is that Russia murders its own oligarchs the second they fall out of Putin’s favor, and ships anyone who holds up a blank sign in protest of the regime gets shipped off to the front lines. No way that man would survive a second if he ever went against the party line. Which means he hasn’t done so.

A simple no would have been sufficient. I’m not interested in baseless speculation. I had hoped you had actual evidence, which would intrigue me greatly. As it is, I have someone’s imagination put to paper.

If I were him, I’d get on the next plane to the US and happily spend the rest of my life in Leavenworth rather than allow myself to become a propaganda tool for a bunch of genocidal fascists.

He’s not saying anything. He’s not being a propaganda tool. You can make a rather weasily attempt to say his not denouncing something is in essence supporting it and thus being a propaganda tool, but that’s a stretch and rather disingenuous.
