Renting doesn't excuse the overreaching nature of DRM however, and its usage of presumption of guilt. I.e. such level of control is still unacceptable. Besides, all that is purely theoretical in case when the rented digital product isn't available DRM-free for purchasing (which can be pointed out to as an option for those who don't want renting). And in case of video, that's exactly the situation. I.e. it's not DRMed because it's rented, it's DRMed because they just want to always DRM it.
