You think geo restrictions are, well, restrictive? Enter OS discrimination
Do you think that geographic restrictions are obonxious and annoying? You haven't seen the rest of ebook hell.
Consider buying an ebook in a common format with copy protection, such as an ePub file with Adober DRM. What if you don't use a mainstream operating system like Linux? You are out of luck.
As far as I know, such a file can be legally accessed only with the Adobe Digital Editions software, which is available for Windows and MacOS X. Adobe considered porting it to Linux, but scrapped the idea.
None of the available legal options for getting an ePub ebook with Adobe DRM on an ereader via Linux are practical:
* get a -- possibly virtual -- Windows or MacOS X machine, or already have a spare one
* borrow a Windows or MacOS X machine
* jump through hops to make Adobe Digital Editions work on your Linux system, which may or may not work and break at any time
* never buy ebooks with Adobe DRM
* any others?
This is what a couple of consumers might decide to do instead:
* remove DRM
* not buy the ebook in the first place, and go to the dark side
