You're using the word "culture" as a shibboleth for a whole package of entitlements that people on message boards tend to believe in, and not in its conventional sense. Simply labeling my work as "cultural" does not entitle the world to access that work for free; it's my work.

Ironically, you play the opposite semantic game with the word "monopoly", whose technical meaning has already been clearly fleshed out upthread. If all "monopolies" are immoral, then you don't believe in property. Really, though, you're trying to repurpose that word for emotional impact instead of understanding; you mean it as "property rights asserted by people we don't like."
