I think you are viewing censorship apparatus as on a good -> bad spectrum. There is also the spectrum of the scale of censorship. For example: HRC's "sex ring" (obviously false facts misrepresented as the truth) is fake news that should be suppressed. But on the flip side, we obviously don't want a USSR-style control of the press, where the wrong word/opinion can land you in the gulag.
You seem to think that because any kind of censorship apparatus can be subverted for nefarious means, you should have no censorship apparatus at all. But I'll counter that that in itself is a form of intellectual laziness: Should we not explore the possibility of building a decentralized apparatus with appropriate checks and balances, that keeps the bare minimum of "fake news" out of general circulation? The answer may be no, but we should at least explore it.
