To the casual reader there may be some missing context here so let me fill it in. The overwhelming majority of “print disabled” persons in the USA are blind. The Library of Congress is funded to provide gratis talking books[1] for that community and provides an app that understands the DAISY format. There are also dedicated devices, but I don’t know anyone that uses them anymore.
While I agree with you that better accessibility is good for all users, your framing of this is a bit offensive[2]. I know you don’t mean to be, but you’re framing a big accessibility win for a community that faces serious everyday challenges as somehow being bad. Maybe don’t do that?
Edit: There is the potential for a big mutual win here. If sighted persons could pay fair value for DTBs, it would incentivize publishers to make more titles available. We would get the format's benefits and the blind community would get access to more titles.
