Yep, it looks like WotC's lawyers have now infected the Tolkien Estate and by extension Cubicle 7. Because, as you well know, offering your product in a digital format means thievery. Which must be why RPGNow does such great business.
This is in addition to Cubicle 7 canceling the GenCon Book release of The One Ring Collection: GenCon 2012 Edition.
No stated details as to the why for either, but with licensed products there are always too many cooks involved in the process.
