Who is hurt by the decision of authors and publishers to turn off text-to-speech?

People who are blind or have low vision; students who need textbooks in an accessible format; people with dyslexia; people with brain or spinal cord injuries; the elderly who are losing vision; stroke victims; people who are learning to read; people for whom English is a second language; people with a physical disability that makes it difficult or impossible for them to hold a book or maintain a comfortable reading posture; and other people who have processing issues that make it difficult to read print are all examples of people adversely affected by the decision of authors and publishers to “turn off” text-to-speech in Kindle 2 e-books.
