Animation teacher faces the sack for refusing to push "unnecessary, expensive" textbooks at hedge-fund invested Art Institute of California

Mike Tracy teaches at the Art Institute of California—Orange County, but not for long. In a note on his Facebook page, Tracy explains that AIC-OC (whose parent company, EDMC, is 41 percent owned by Goldman Sachs) has told him he'll be fired if he doesn't agree to sell a quota of expensive and, in his opinion, unnecessary e-textbooks. Here's the note Tracy posted:

As many of you know, I have been in a dispute with our school, the Art Institutes, for some months now, over their policy of mandatory e-textbooks in classes where their inclusion seems arbitrary, inappropriate and completely motivated by profit. In July I asked the US Department of Education, the California Bureau of Private Postsecondary Education and WASC (our accrediting agency) to look into my concerns. Since that time, the school and its parent company EDMC have escalated the pressure on me to select a book for a class I teach that I don’t think requires one.
Today, the President of the school, Greg Marick, presented me with an ultimatum; either choose a book by Tuesday, Aug 14th or the company will terminate my employment for insubordination. My response, of course, is that I will not change my mind on this issue and that I’m determined to resist the policy however I can. I think this means that, as of this week, I will no longer be teaching at AI.
I want you, my students and colleagues to know that it has been my great honor and privilege to have worked with you over the last 11 years, and that I will miss the opportunity to work for you and with you. I have enjoyed my time as a teacher very much, but it appears as though it is now time to move on. Furthermore, you can count on me to continue the struggle that I have instigated on this issue, if only from the outside. Although it ain't over till it’s over, it looks like a 99.5% deal, barring an 11th hour change of heart by the corporation, which would surprise me.

Here's a petition from Tracy's colleagues and present and past students, asking the administration to reconsider its position.
