I'm finding it harder and harder to swallow the "scanning the computer for ebooks outside of ADE's library" portion of the claim (not that I'm excusing the transmission of ANY--clear-text or encrypted--personal data). If not a service, then a separate thread/process would need to running while ADE was open to actively search for ebooks on the computer's hard-drive. Something like that should be trivial to detect.

I open epubs that "aren't in my ADE library" (and in fact only exist in my calibre library) with ADE all the time. It's called "Open-with." Neither the OS-level file association method, nor the plugin of the same name for calibre actually "adds" an ebook to ADE's library when employed. I find that to be a more likely explanation for calibre-only titles appearing in an ADE generated log-file, than a rogue process scanning your physical media for titles.

None of which addresses the issues of the transmission of the data that has many disturbed mind you, but I'm just going to need to see some more compelling evidence supporting the claim that details about books that were "never" opened by ADE are being actively sought out and collected.
