If they did such, then they could track the movement of the ebook, whenever the device it resides on connects back to their store, during a Sync etc.

What you are referring to is known as "watermarking" or even "social drm". This is not a problem for most people, who simply wish to have a future proof backup, read their book on some other device or perhaps some other purpose like enabling text to speech or copying.
