I will buy more of their Hardcopy because of this decision
I have close to 3,000 hard and softcover science fiction books from the last 30 years and probably another 1,000 of old technical/instruction books that go back to early 1900's.
I will gladly purchase more from Tor specifically for their decision to get rid of DRM even if I am no fan of E Books.
Call me a luddite but I like physical media, especially books. There is substance and permanence with paper books that just cannot be had with E Books.
When technology fails, paper books can always be read and they have no DRM or region codes and they can't be retracted like Amazon did with Orwells 1984.
Rules, regulations and technology that can or do interfere with the availability of knowledge are among the most despicable things on earth. The 1% wants the 99% to be an unknowing, unquestioning "Idiocracy" and they cannot be allowed to win. DRM is only one front against the 1% that must be conquered.
