What's an example of an internet champion that's not a web one?
The obvious difficulty is there's little money in it, as the benefits are distributed throughout society rather than captured by a centralized company. My overall point is that looking towards the tech giants to defend our own rights is folly.
(They do interface with several early Internet protocols such as SMTP. But that's better looked at as mining content from non-web protocols, which they'd have no intrinsic problem deprecating like XMPP)
