How is it possible that Textop would ever make use of proprietary works?
A. There are at least two ways to do this. First, we might pay publishers for the right to use certain works, and make access to those works via Textop a “premium service.” Second, we might (after carefully considering the practical and legal ramifications of this) make proprietary works themselves accessible only to people actually working on Textop, while the general public sees only the summaries of chunks of the works.
