I have great sympathy for teachers. I think teachers will resource their classrooms by any means at their disposal. At the most expensive, educational resource purchasing was less than 1% of educational budgets before this change. The wholesale move to this copying regime has meant that teachers and their schools and systems are, more and more, looking to open-access resources that have to be supported by money from somewhere, or they're looking to resources cobbled together by teachers from whatever they can find from available sources, often digital sources.
