But that's nonsense. If the EFF hands me a binary for an app, it hardly matters whether it's DRM'd or not as long as I can still run it. The extreme minority of people are capable of doing anything remotely interesting with a binary without access to source code. If the EFF wants people to be able to adapt and customize their app, all they have to do is release it under a permissive open-source license.
In fact, if this really was a purely moral stance, they could have developed the application and released the source without ever publishing it to the App Store, thus allowing users to compile and use the application themselves. But they didn't do that. Instead, this seems to just be a flimsy excuse for the EFF to make a bunch of noise about Apple in order to drum up some PR.
