This is naive. Every piece of software has bugs. Once you make it a ROM, you can't easily fix it. On the other hand, a DRM enabled piece of hardware can always receive a bug-fixed non-modifiable binary quite easily.

I think the problem with some consumer devices may be related to legal constraints here. For instance, mobile phones and other devices that emit variuos frequencies at various power levels may need to be non-modifiable by the user. Otherwise, these devices wouldn't get use approval at all.
PS. I'm just pointing out the facts here. Not taking sides.
