The criticism the original post has of WebBundles is fundamentally technical. All of their privacy and anti-adblocker claims stem from the idea that the bundles have special URL randomization powers that the current one-resource-per-request model can't replicate.
If that technical basis is incorrect, the whole thing just collapses. There's nothing left. Not allowing disproving the technical basis of these kinds of posts would mean that we have to just accept conspiracy theories at face value. That does not seem like a healthy outcome.
(Or to put it another way: you wanted to discuss "how this technology will be used". But how can we possibly have that discussion without agreeing on "what the techology can do" first?)
