OpEd, Charging for The Free - Tim Holt, El Paso Herald

I am amazed with the ability of companies and education organizations to charge for things that should be free. For instance, I once was on a panel discussion at a conference explaining how my district had adopted the free CK12.org Flexbook model for our High School core subject texts. I also spoke of Rice University and their Open STAX textbooks. Again, free to use, free to share, copyright free and updatable at any time. There are actual companies that sell free stuff! I was amazed. https://elpasoheraldpost.com/op-ed-charging-for-the-free/
