Libertarianism is a broad ideology that means different things depending on who you ask. The notion that an authoritarian government can be controlled by billionaires and corporations is certainly viable. Undermining those forces and resisting their control by by not paying for content and controlling your access to said content by having your media library is exercising personal liberty.
The comment I made was quite nuanced and I mentioned that I'm personally more inclined to socialism and liberal views, but hopefully not too ideological that I can't see value in different ideas.
