I strongly suspect MBF is an actual Intelligence operation of the US Government.
It makes all sense that to control the information that people access in this day and age of people being able to read news from just about anywhere using the Internet and when there is widespread awareness of Fake News and similar opinion making mechanisms, for a state to set up and fund an intelligence op disguised as a "well intentioned group" to act as an "independent" (always without the transparency, clear processes and supervision to guarantee said independence) gatekeeper to all that information and tell people which information sources can be trusted and which cannot.
With such a scheme you can even get infiltrated agents in popular social media (such as moderators in high traffic places where anybody can be a moderator) to leverage that "well intentioned group's" image of "independence" to get both soft (advice bot) and hard information control mechanics in place (post rejection) determined solely by that single gatekeeper's decisions.
It doesn't even take a conspiracy, just a handful of individuals and some careful talk and image management to sway well intentioned people who aren't exactly trained in data analysis or counter-propaganda to "use these nice and honest people to protect our readers from fake news" - people seriously understimate just how much influence a person who is paid to spend all day gaining influence in open groups, who has done it long enough to be experienced at it, who has zero ethics or honesty and who has access to the level of resources a nation state can provide, can gain and then leverage.
