One of the things that characterizes our culture in Cybernus is language.
As we aimed to be an ever evolving civilization, it was decided that our language should then be, also, ever evolving. Once a month, during The Update -our most significant celebration where new discoveries, thought trends, etc, were presented to the population at large- a time was reserved for the ritual of language renovation. A number of random words, somewhere in the range of 30 to 50, were marked as outdated while a similar number, again from 30 to 50, of new words was introduced into the language as the words to show you were current with your civic duties of evolution and progress.
Usage of so called outdated words wasn't re-classified as a crime until much later, and only as a way to better enforce the goal of Continuous Progress. For some time you were just seen as an outcast or simply as one of the billions of poor people. Poverty was not so much defined in economic terms mainly because it wouldn't have meant much, with what happened in 2043 and all that. Instead being poor now meant you were someone that did not have access to enough information to participate in the careless happiness of Continuous Progress. But as I said, not keeping up with language evolution is now considered an offence and repeater offenders are forced to undergo re-adjustment.
Of course, after a short period of going through this, it was noticed that it's not so easy to continuously come up with new words and not make the language a unintelligible garble. And so words are recycled rather than discarded, which was a wasteful and unsustainable thing to do anyway.
