The only description of the service in that article comes from the publishers' complaint, and makes it sound like Boundless provide little more than a photocopy of commercial textbooks run through a ransom-note filter.

Yet "When asked to describe how his company pulls together the open-education content to produce its digital textbooks, Mr. Diaz declined to elaborate on the process" and so the publishers ended getting to establish the first and only concept of the company to a huge audience. And it's not like people can check out the website for themselves, since it's in closed beta.

Staying quiet here really doesn't seem to have been the best strategy.
