Whose money? Important to determine whether the student or the institution is the winner here. Are we increasing access to high quality resources? I think the answer is yes, but I think it also bears thinking about.

Another type of savings to consider: the technical debt that students of all ages incur when they encounter a new technology that may or may not be well supported. If OER is trapped inside proprietary technologies with unique logins, it's worth considering how many of those resources we ask students to grapple with over the course of a degree.
