Libraries might not be a business but they still have to compete for funding. If those funding them think they are no longer relevant, the alternative is to slowly lose funding and die. People don't care about books anymore, so if the library must dangle an enticement to keep people engaged enough to retain the instilled indeed that knowledge should be freely available instead of siloed (and the other benefits of libraries), so be it.

Adapt or die is the way of life.
