> If “free” belongs in the definition of OER, which I believe it does, it belongs there not as “free plus permissions” but as “a free grant of permissions.” Many of the 5R permissions are available in traditionally copyrighted materials if you’re willing and able to pay for a license. What distinguishes openly licensed resources from traditionally licensed resources is that the 5R permissions are granted to you for free by the open license.
