'the free world' loses internet content mostly because we are indifferent and don't value the humanities or social sciences as much as we used to.

china loses internet content because it is a one party state dictatorship that is purposely trying to eradicate the cultural artefacts of it's victims and opponents, by hiring masses of people whose career goals are the purposeful destruction of memory.

we do have examples similar to that, for example "free speech advocates" like Peter Thiel and Elon Musk who abuse the legal system to silence critics. But those people are not literally running the government in a government that will never change hands.
