Charlie Stross thinks is it foolish for the Big Six book publishers to insist on digital rights management on ebooks because it just gives Amazon more power:
Anyway, my point is that the Big Six’s pig-headed insistence on DRM on ebooks is handing Amazon a stick with which to beat them harder.
DRM on ebooks gives Amazon a great tool for locking ebook customers into the Kindle platform. If you buy a book that you can only read on the Kindle, you’re naturally going to be reluctant to move to other ebook platforms that can’t read those locked Kindle ebooks — and even more reluctant to buy ebooks from rival stores that use incompatible DRM. Amazon acquired an early lead in the ebook field (by selling below cost in the early days, and subsidizing the Kindle hardware price to consumers), and customers are locked into the platform by their existing purchases. Which is pretty much how they gained their 80% market share.
An 80% share of a tiny market slice worth maybe 1% of the publishing sector was of no concern to the big six, back in 2008. But today, with it rising towards 40%, it’s another matter entirely.
As ebook sales mushroom, the Big Six’s insistence on DRM has proven to be a hideous mistake. Rather than reducing piracy[*], it has locked customers in Amazon’s walled garden, which in turn increases Amazon’s leverage over publishers. And unlike pirated copies (which don’t automatically represent lost sales) Amazon is a direct revenue threat because Amazon are have no qualms about squeezing their suppliers — or trying to poach authors for their “direct” publishing channel by offering initially favourable terms. (Which will doubtless get a lot less favourable once the monopoly is secured …)
If the big six began selling ebooks without DRM, readers would at least be able to buy from other retailers and read their ebooks on whatever platform they wanted, thus eroding Amazon’s monopoly position. But it’s not clear that the folks in the boardrooms are agile enough to recognize the tar pit they’ve fallen into …
[*] It doesn’t reduce piracy; if you poke around bittorrent you’ll find plenty of DRM-cracked ebooks — including all of my titles. DRM is snake oil; ultimately the reader has to be able to read whatever they bought, which means shipping a decryption key along with the encrypted file. And once they’ve got the key, someone will figure out how to use it to unlock the book.
