Run that modified software on some other competing DRM-less hardware?

For good reasons. Hack-resistant safety critical stuff and etc. And 
for TiVos (and alike) both hardware and controlling software is a 
loss leader. They want the boxes to be used as intended to generate 
profits. My, what a felony it is in the GNU land.



The technology to secure the first sale privilege exists today. As 
will be explained further below, copyrighted content can be delivered 
to the consumer with digital rights management ("DRM") systems that 
enable secure electronic transfers of possession or ownership, and 
that protect against unauthorized retention of the transferred copy. 
Extending the first sale doctrine to the electronic environment will 
provide the incentive for development of newer, more flexible, and 
more efficient DRM tools.
