Honestly I'd prefer they put a big skull-n-crossbones logo on the cover of any book that's not DRM-free, but this will do. I wish I could search in a pool of only DRM free titles, or browse by DRM-free only. Yes, I like to own the comics I pay for that much.
Let's see, I can buy Gail Simone's Red Sonja runs now, I can buy Warren Ellis' (and Chris Weston's) Ministry of Space, much of Mike Allred's Madman (and IT Girl, which I don't believe Image has up on their site?). Oh my Gosh Garth Ennis' (and Amanda Conner's) The Pro. Tobin and Coover's Bandette looks absolutely gorgeous, I'll have to check that out. Looking at books written by Alan Moore, From Hell is DRM-free but not Lost Girls? They're both Top Shelf. Hmm, so we do need to keep our eyes out, it's not necessarily catalog-wide. I guess no buying from the Comixology Android app for me until it also shows whether a book is available without DRM.
I haven't seen anything about download limits (for instance if we can only download once per comic) or anything like that. Hopefully Comixology won't allow that to be an option, sometimes backups get lost or corrupted, you know.
For those worried about DRM-free comics ushering in a new age of piracy, the sky isn't falling, I promise. If the big publishers are worried about piracy well guess what, every comic they have DRM-protected on Comixology is already freely available on some torrent site. DRM-locking them didn't stop the piracy, in fact it punished paying customers by giving them an inferior product to what torrenters are downloading for free. Yes think about that for a moment. How could DC or Marvel know that I, a (theoretical) Comixology customer, am not a pirate? Because I'm paying money for the book instead of downloading it from The Pirate Bay. Maybe don't punish people who want to give you money, you know?
There were rumors of this news floating around a few days ago. I speculated (to my friend, not on this blog) that Image would be down for DRM-free Comixology (of course), and I guessed Dynamite too, because they've recently participated in big Humble Bundle comic sales. IDW has too with a Dr Who bundle, so I guess they're not much of a shocker either. I'm pleasantly surprised by the rest, and I'd love to be surprised still by a full list of DRM-free publisher and titles. Anybody?
