I completely agree. The issue is that these are 'free' 'as is'.

The correct solution should be an exemption for public access/domain materials, which OTHERS can provide additional materials for as they desire, from being compliant.

There is a difference in contributing to the common good, and discriminating against differently-abled CUSTOMERS.

This is a great example of where a different group, such as a charity or some group benefiting from it (maybe students who produce and release to P.D. transcripts for extra credit) could continue the effort of making the content a more vibrant part of the knowledge of our species.
