Originally licensed and published under a Creative Commons license that allows anyone to republish and sell it, Godin objected that it was dishonestly sold as a new edition. The publishers then put it out with a note that it was the same edition as the free one available on line. The author accepted that.
Nevertheless, the fact that the book was for sale produced some criticism of Godin as he could have put it out under a different Creative Commons license that allows anyone to make use of a published work but only on a not-for-profit basis.
It seems to me that the critics have got that wrong. Many people are willing to pay for the convenience of having a hard copy version and producing that has costs. If there is a profit involved, as some critics objected, that motive got the book printed. If the price were too high, others were free to print it as well, likely bringing the price down.
The consumer was well served here, better than if it had been put out under the more restrictive Creative Commons license.
