The overarching point still stands. That people being in favor of censoring "disinformation" (ie speech by private individuals) in certain instances but not others is an inconsistent stance that carries a distinct appearance of partisanship.
A few of them are plain-old voter suppression, and ~50% of the time, people in power find them incredibly convenient.
You don't see them very often, because in most free countries, trying any of them is an incredibly serious offence.
