I know nothing about this suit other than what I’ve read in that linked article, but I suppose it’s not entirely surprising that indie booksellers would want to get in on the eBook action — heck, I want them to get in on it too, since I would be happy to send some of my eBook purchasing cash to my local bookseller — and see DRM as a way of locking them out.
Likewise, I would be curious as to how Macmillan’s DRM-free stance (via Tor, which is my primary fiction publisher) has an influence on things.
This would also be the place where I note that in the US, at least, the two biggest publishers of my fiction, Tor and Subterranean Press, have no DRM on any of my eBooks at this point. So buy with the confidence that comes from knowing you can put my fiction on any e-reader you damn well please. Because we love you, dear reader. Yes we do.
