Australian authors, songwriters, musicians demand payment from AI companies

Individuals, educational institutions, and other organisations have to make payment in some form or other to access the work of writers, musicians, artists, and other creatives. It seems like a naive question, but why should it be any different for the tech companies who are presently helping themselves to whatever material they can get their hands on, so as to train their AI agents? Particularly if the same tech companies expect users to pay to access their AI products. Of course all writers, artists, musicians, etc, wherever they are, should be receiving compensation if any of their work is being used to train AI agents.
