If the same entity controls the proxy and the target, what's the actual gain in privacy? Also, if this were to be the actual deployment model, we would again be building a huge centralization mechanism for the entire web. I am always baffled by how a community that often seems obsessed with potential censorship and surveillance by governments then actively adopts architectures that foster potential censorship and surveillance by private companies, or create new gatekeeping opportunities. More precisely, the risk is that this model would foster the birth of something that I'd call a "RDN" - request delivery network. Let's suppose that, like for CDNs, we end up with very few global providers managing the proxy layer. What happens if one of them goes down? What happens if they agree among themselves, or are forced by external factors, to deny requests from or to specific addresses, networks, or countries? Also, why should someone provide such a service, if they don't find ways to monetize the data? Is this creating economic incentives to attack the very privacy that the new architecture is supposed to offer? Or to ask application developers for money? Or to make certain client applications faster than their competitors by refusing service to the others, or by providing downgraded service to some of them? This may or may not happen, depending on how many proxies will actually be available, but given the degree of consolidation that we're seeing in similar services, I would expect this concern to be recognized and addressed from the start. I didn't see any such consideration in the draft or in the charter. Also, I did not see any requirements taking into account that, after all, there are sources that need to be recognized (e.g. bots) and destinations to be blocked permanently (e.g. illegal content) or depending on who the user is (e.g. parental controls). This should also be addressed explicitly by any proposal. -- Vittorio Bertola | Head of Policy & Innovation, Open-Xchange vittorio.bertola@xxxxxxxxxxxxxxxx Office @ Via Treviso 12, 10144 Torino, Italy
