Edited to add - To be clear for anyone, it’s Oligarchs/Billionaires paired with rampant, unfettered corporate greed. (at least in my view)

Here are some visual aids to accompany my clarification:
It means non-authoritarian and anti-capitalist. The US version of libertarian, which are just capitalists that want the market to be the government, is not the definition of the word.
Unfortunately, though, it is now. At least here.
On that note, you know many words have multiple definitions, so even if a definition colloquially exists, that differs from the one of most wide use, doesn’t mean that in that local, the wider use case is suddenly void.
