Also Kobo's ecosystem exhibits many of the same DRM problems that Amazon has. The majority of book publishers still require DRM. You get DRM locked copies regardless of if you buy them from Amazon or Kobo (or Google Play Store).

Some of this post just seems that an "Android Authority" only just now realized there are less-forked Android-based e-readers versus Kindle and they feel happier with the Android ecosystem (and its DRM) than Amazon's. To me it feels a bit like a choice between Purple Drazi and Green Drazi. Many of the same problems but a different ascot color.
