A major issue is that it's not just reading the file, it's that ADE is needed to even authorize and fulfill the download. Then the possibility of DRM on top of that.
While I've never tried it, it's my understanding that you can use calibre to remove the drm encryption on a purchased ebook so you can read it with something like fbreader (which, as far as I know, can't read a drm-encrusted ebook).
Calibre is also available as an appimage.
