It is tempting to label those calling for restrictions on "fake news" sites as halfwits[^1], but this would be misguided. These people are, at best, useful idiots[^2], and, at worst, malevolent actors. Restricting the twin freedoms of Speech and of the Press is almost invariably one of the first orders of business for authoritarian regimes[^3].
In the case of Google and Facebook, the latter of the two assessments is almost certainly the more correct. Other actors[^4] fall somewhere along the spectrum between the two points. In any case, their ends are dangerous and should be vehemently opposed.
Either representative governance is a good idea and the people can be entrusted to acquire their own information and to make their own decisions or representative governance is a bad idea and should be abolished. The constant creep of half-measures from the Left, slowly eroding the foundations of the Republic (and of representative governance the world over) is as disingenuous as it is dangerous. Anyone who believes the current push will end with "fake news" sites is terribly mistaken.
