Wikipedia's co-creator has revealed the moment he learned the CIA and other intelligence agencies were hijacking public entries for their own benefit.

Larry Sanger appeared on Tucker Carlson's podcast to claim Wikipedia had lost its way and began censoring accounts which held right-wing or conservative views.

'There is a whole army of administrators - hundreds of them - who are constantly blocking people that they have ideological disagreements with,' he said.

'Over the years, conservatives, libertarians, were just pushed out.'

While Sanger maintained he was unaware if there were 'puppet masters that were controlling the process', he did admit that sometime between 2006 and 2007, he began asking questions about intelligence agencies interfering with the entries.
