It is very cranky, no denying that.
The founder of the site, Robert Parry, uncovered US involvement in Contra cocaine trafficking during the 80s. Nobody denied the facts, but by the time the story came out American political culture had become more conservative (Reaganism) and people weren't as interested in hearing about covert crimes the way they were in the 70s (Watergate).
Parry got drummed out of the journalism for not towing the line and became somewhat bitter. It's not my only source of news, but it can be refreshing to read something that quickly attempts to poke holes in mainstream narratives.

> But anyway, accusing an organization of having a pro-USA bias isn't a strong criticism against a domestic USA project.
There are laws against domestic propaganda. For instance, the CIA is not allowed to plant stories in US media.
The German Marshall fund is part of USAID and USAID was founded by the members of the CIA. They're sister organizations that service the same political goals. It should raise eyebrows that USAID wants to construct a domestic propaganda operation.
