But since they publish that info for mass consumption...I'd say these guys aren't "skirting" the GPL as much as simply and blatantly violating it.
But I will grant that if they are trying to skirt by this on defining themselves as a "web service" then you could either change the license or simply better define web service, which is what is being done. However, I don't think it would be necessary if someone wanted to sue them for violation of the license. Reasonable man theory and all.
