What specific US based leftist media are you accusing
none, but there is plenty of us corporate and state sponsored propaganda posted in these communities and i don’t see accusations of shilling for the pentagon and cia being thrown around like the accusations of shilling for putin/trump
i never suggested any obligation. i’m saying that it’s unreasonable to disqualify factual reporting on the basis that you don’t like the people that funded it. object to the framing, or even to the actors themselves, but the reporting of facts is done by all kinds of actors, and it’s up to readers to understand biases in even factual reporting and come to their own conclusions.
