This is meant to show that the housing can be made of wood, but the antennae and electronics still require mounting points via metal or plastic fasteners. The article gives a few reasons why this might be valuable, eg fewer toxins released during burnup, but I see this as an experiment in alternative manufacturing techniques, to see what we might be missing when we assume things like this need to be made out of metal and bolts.

That's an optimistic view, I suspect it's just done to get people talking about it and to contrast the traditional joinery against the technology. There isn't likely to be any criteria by which wood is the best material to use for something like this.
