I think the "unusability" of the GPL is exactly what many people want when they release GPLed code. GPLed code can be used by other researchers (good for popularity), but you can't use it for proprietery software.So if Adobe wants to use this curve, they have to license it. If it actually works out, I don't know, but that's been the intention of some researchers that I asked why they used GPL.
