Great observations and perspectives from Ben Crowell.
We from CK-12 Foundation (www.ck12.org) are also participating in this initiative. What this initiative allows is to have Teachers presented with choice of books "from other great authors like Ben Crowell" and not just one provider. Irrespective of this initiative, the commercial publishing houses have dwindled down to 3 main stream companies, ending up in an oligopoly situation. It is also worth to note that there are superior materials from NSF funded projects which are available for free. Some examples of NSF funded projects are:

as well books created by other states like Virginia:
