Not true. I think you'd find if the edges did a very simple thing
(encryption of all traffic), that network owners would *have* to involve
the edges in policy, and market forces would cause the network owners to
seek to please customers rather than control them.
ln other words, the networks would have to "sell" policy as a benefit to
users, rather than to enrich themselves.
And this is something the edge users can do unilaterally, for their own
benefit. They do need to be enabled by toolmakers, which means software
vendors. Microsoft *is* the problem, at least metaphorically, because
they have stopped selling benefits to users, and started viewing the
network owners as their customers. (rather than the sources and sinks of
information - the users).
Thus it isn't incompatible with market-based capitalism at all! It is
incompatible with monopolistic capitalism (known as feudalism
It's worth noting that we had end-to-end encryption in the original
Internet design - it was viewed by a number of us as essential in the long
term, and we had designs and implementations ready to go in 1976-1977.
Had we not been actively blocked (and not for market-oriented reasons) from
doing this, we would have had a much more robust and innovative platform
today. (and not because of imposition, but because it would have become
part of Internet culture).
