Of course, odds are that it won't stop the device phoning home to tell them what you've got so that they can update their recommended lists for you, even if you don't see them (and if you use the desktop, you can't turn 'em off). Worse, it's sending info off to Google Analytics when it does. The only way to go is revert to 1.9.14 and never connect your Kobo to the desktop software or allow it out of airplane mode...
