Hacker gets annoyed at Amazon’s Kindle apps, reverse-engineers the Kindle web reader’s protocol (which basically sends each page as a set of glyphs in a deliberately broken variant of SVG). Such obscurity, much security.

@acb I highly respect hacktivisms like this, but I think making a blogpost explaining how you did it is not the correct way how to share it.
Your solution should be heavily obfuscated, not talking about details, and just making an obsfuscated extension or an app that "just works". Don't make it easier for them to fix.
I kind of understand that may be suspicious and have it's own risks for the user, but still feels like a better way how to go about it.

As technology plays a central role in many facets of our lives from communication to purchasing goods, enrolling in classes and seeking employment, it is important now more than ever to bridge the digital divide between technology and people with disabilities. In 2006, DRA represented the National Federation of the Blind and three blind plaintiffs … Continue reading » "National Federation of the Blind (NFB), et al. v. Target Corporation"
@acb Always love to see when folks that run into an artificial barrier and happen to have enough skills and willingness to learn get past those barriers.
Though for those that care (I am not sure how long it will keep working). If you get a copy of the Kindle for PC app that did still have the download option (2.4.0 70904). You can still sign-in, download, and strip DRM (or just read if not trying to use other apps/formats). Just need to make sure to disable auto-update first thing.
