It's definitely an authoritarian measure as it involves a central entity interfering between two third parties (Facebook blocks a newspaper from talking to you). It can also be seen as having a left bias because it seems to imply that owning money and buying mansions is inherently bad (why would they hide it, otherwise?) and therefore that rewarding people for their work (even when you don't agree with the nature of their work) is wrong.

Liberalism is a tricky word, because Modern Liberalism or Social Liberalism (or just Liberalism in the USA) are almost the opposite of Classical Liberalism.

The Political Compass avoids the terms and use:

- Authoritarian (Fascism) - Libertarian (Anarchism): from "everything is controlled by a central entity" to "everything is decentralised" - Left (Communism) - Right (Neo-liberalism): from "everything is nationalised", to "everything is provided by the market"
