I have been reading their articles for months. I guarantee you that bias still shows through. Even in their "toned-down" state, I have felt my ears get red reading some of their articles.
They have hardly been warped to be "pro-US". I would be more concerned if their voice had actually swung to be "pro-US"; as things stand, they seem to have gone from "extremely critical of the US" to "still critical but a little nicer about it".
