I think the author significantly misrepresents the argument against copyright assignment. The issue is not the overhead, the issue is control. If you assign copyright to e.g. FSF then FSF has the exclusive right to relicense to whatever they want. Maybe in the case of FSF I trust them not to abuse this power, but in several recent cases this has been used to relicense projects to be effectively closed source---which is almost certainly not what any independent contributor wanted done with their contribution. The DCO is a compromise that retains protections for the project but also avoids stripping contributors of their rights, which is a safety mechanism of sorts against unilateral relicensing on the part of the original developer.
