That may be true but until a better solution for ebook lending exists, libraries in their current form using Libby / Overdrive is still an enormous public benefit and is a direct service from local taxes that benefits humanity.
I don’t agree with Overdrive’s practices but I absolutely don’t hold libraries accountable for that because they can’t control what the market offers.
That’s not their fault. Libby / overdrive is what the market offers. If a library wants to loan digital books, that’s the answer. This is a competition and marketplace and monopoly problem. Not a library problem.
