What is DRM?
To quote Defective by Design;
"Digital Restrictions Management is the practice of imposing technological restrictions that control what users can do with digital media. When a program is designed to prevent you from copying or sharing a song, reading an ebook on another device, or playing a single-player game without an Internet connection, you are being restricted by DRM. In other words, DRM creates a damaged good; it prevents you from doing what would be possible without it. This concentrates control over production and distribution of media, giving DRM peddlers the power to carry out massive digital book burnings and conduct large scale surveillance over people's media viewing habits."
Since DRM requires software to be proprietary to work effectively, a DRM scheme cannot work if we can share a modified version of the same program with the offending code removed. Free software and Trisquel are resistant to this kind of control but are not immune.
Free software can be restricted by means of Tivoization, named after the device where it was first seen on. Tivoization is the process of creating a system with incorporates free, copylefted software and, through the use of proprietary hardware restrictions, users are unable to run modified versions on the same hardware. Any 'free' software used in this manner is not free software. This is one of the many reasons why Open Source Misses the Point of Free Software
You may have encountered DRM with proprietary software:
- you have a video on your laptop, and may not show it on a larger ("unauthorized") screen
- you buy an ebook on your phone, and may not read it on your computer
- You cannot install your modified version of a system on the same hardware due to hardware restrictions despite the software being 'free'
DRM's side-effects
Remote deletion
From the New York Times' story on Amazon and 1984:
- “It illustrates how few rights you have when you buy an e-book from Amazon,” said Bruce Schneier, chief security technology officer for British Telecom and an expert on computer security and commerce. “As a Kindle owner, I’m frustrated. I can’t lend people books and I can’t sell books that I’ve already read, and now it turns out that I can’t even count on still having my books tomorrow.”
Surveillance
DRM sometimes incorporates service-as-a-substitute-for-software (SaaSS). SaaSS raises surveillance concerns as a matter of course.
Like when the client software remembers which books you have read, and which page you are on. And saves that information on the vendor's server, instead of on your device.
Vendor Lock-in
DRM forces you into a position where you are dependent on a single entity for products and services. Switching between vendors becomes incredibly difficult without incurring massive switching costs.
