Part of the strategy employed by mainstream media to misinform the public is _selective_ reporting. That is, either the entire event is not reported if it doesn't fit the narrative, or parts that don't fit the narrative are simply omitted or deemphasized. Will FB detect and demonetize that as well?
Then it's just one-sided censorship in favor of narrative peddlers who run major media corporations, and it has nothing to do with suppressing "fake news".
