Not sure if it's a good example, keep in mind that at the first
exploitable software bug any hardware DRM breaks apart.

But since you made a BSD-embedded example, this shows how the only
really important thing is that by using linux instead of BSD, they
can't make huge improvements or important security bugfixes to the
routing engine, without us being able to incorporate them in our "home
firewalls", that's the whole difference with BSD and it explains the
spirit of the gpl pretty well and in the end why linux by definition
can receive more contributions and in turn be technically
superior. Whatever the vendor does with the gpl code is generally up
to him, and if it uses the closed approach it'll allow somebody else
to sell a "open" router (potentially at an higher price). Economy
101. The worry that nobody will step in and sell an "open" equivalent
is a red herring. Infact I wouldn't be so certain that openmoko would
exist if the current linux cellphones would be already totally open!
Now I know this all probably sounds boring talk, but I think it's much
closer to reality than the prospect of a trusted computing and/or DRM
apocalypse.
