Also the Kindle is marketed as allowing you to put your own documents on it.
Yes Amazon want to stop you reading books licensed from then on anything but a Kindle but not the other way around.
They may market it like that now, but that can change. If Google can stop you sideloading apps on Android, I have no doubt Amazon could try to stop you sideloading books on your Kindle.
Using keys stored in hardware for DRM is industry standard. It's not draconian.

What amazon could block is getting books from other sources onto a kindle. But there's plenty of devices. I use an iPad.
