Also not correct. I've purchased books from many sources and read them on my Kindles and Kindle apps with little trouble.

DRM is also proprietary. I have 2 Adobe DRM-IDs; the DRM-IDs are not interchangeable. Not only that the DRM-ID is tied to an app which Adobe considers as a "device" & not a physical device like a B&N Nook that has a setting for the DRM-ID.

Anyway, I finally bought my 1st kindle ereader a couple of weeks ago. Saying that, the majority of my books are from the Amazon even if I never used a kindle or Amazon app for reading as my Fire HDX is loaded with the play store & CC & Moon+Reader. In fact, my reading is on an android tablet until now.

Right, that's my complaint, although I didn't state it well. DRMs aren't inherently bad, but when they're proprietary you're locked in. It would be nice if there was an open DRM standard for EPUB, or maybe there is and they're ignoring it. For example, web browsers use an open encryption standard to provide a secure connection.
