The techniques and methods of mind control that worked in the past are now obsolete and outdated.

The origin of copyright was the Roman Catholic Church keeping Bible translations for themselves, and not allowing the peasants access to read it for themselves. Then along came the Guttenberg press, and now the Bible was freely available.
