How would this be any different from advertising on certain shows or talk radio that peddle huge amounts of BS and are almost exclusively consumed by gullible people? Again, the point is that the standards followed by broadcast TV are higher than the standards followed by, random media companies that aren't regulated. And what Facebook is doing here aligns closely with how public institutions that are held to the highest standards operate. The general principle regarding the freedom of speech is that the closer you are to being a public institution, the more open you ought to be in terms of the types of speech you accept. So the criticism here isn't merely wrong, it's exactly backwards.
