Using that same logic most statements out of the US corporate InfoSec establishment should be similarly scrutinized.

A whole lot of these outfits are started by former NSA employees, and they love having people that previously worked in US national security on their rooster for the marketing value.

Yet whenever one of these outfits accuses China/Russia/Iran of being responsible for the latest "cyber incident"/"misinformation campaign" these accusations are widely regurgitated without any doubt like some kind of definitive factual truth.
