emen, don't take my words exactly. I just mean that some e-book companies made some dirty tricks to improove their own sales.
As for copyrights:
I know that removing DRM is federal crimes in some countries (even if you had hardcopy, and DRM is expired not supported by software\platform e.t.c.)...
I know that you can be sued even if your children download an mp3 or avi file (even if you allready own an licensed disc with the same content)...
I know that you must pay for every copy of an song for every device you have... (o.k. some companies allow to use one song on up to 3 devices... what a wonderfull option )
I know that you can be sued for listening (broadcasting) of an song in public (even if it was your mobile's ringtone)...
I know that you can be charging for citing an book (or article)...
e.t.c.
so...
I know that some companies will use any trick to made some money (to not start flaming... I'm not talking about EE, but about industry in general) and that's the reason why they protect their devices from "improper" use, or used spyware software to control users.
