Well, that’s not entirely it, actually. The responsibility here is also largely that of the schools and teachers themselves. I outlined in this post the possibility for a school to provide Rhino licenses free to their students for a cost to the school of only 3$/€ per student per year.
The problem is that the schools also succumb to the marketing tactics of Autodesk providing free software to students and educational institutions in the hopes of making them addicts later. “Oh, it’s all free, that’s great…!”
