As I understand it, the claim is not that the US/UK are as evil as Russia, or even more or less morally equivalent. The claim is that the US/UK hoover up online information just like Russia (maybe even more), and that they are more exposed to what the US/UK governments do than they are to what Russia does.

Without minimizing the misdeeds of Russia, without resorting to (false) moral equivalence, it's still a defensible point. (Mind you, I'm not sure I agree with it. But it's defensible.)
