Nice case. Of course this happens only because the GPL is viral.
You know, you might want to save the polemics for a crowd that's less experienced in these matters. With the possible exception of Ken Brown, nobody here's likely to be impressed. ;->
No troll. I just said that to link to a previous point of mine, namely that dual-licensing requires a "reciprocal" license.
[Technically, viral = reciprocal. This has been discussed before. The difference is merely of perspective. Naturally license authors and grantors prefer the positively connoted "reciprocal". Naturally users that find themselves restricted in some way by a reciprocal license (e.g. dual-licensing costumers) will understand and use the term "viral" better. And when discussing that perspective it's correct to use it too. But I see this has a potential of being misunderstood as a provocation of some kind in this list, so I'll try to remember that and avoid it and save us all some time.]
