You could certainly say its ridiculous, but it is (and has been) the basis
for almost all peering arrangements in North America for several decades in
my personal experience.  I believe that the practice came from the telco
world when large telephone companies would exchange traffic without billing
each other so long as the traffic was relatively balanced.  You can imagine
AT&T and Sprint exchange toll traffic and so long as things we're fairly
close there wasn't a big imbalance of traffic to worry the financial folks
over and thus having to do exact accounting on each minute, which was
technically challenging 30 years ago.

That's not what happened.  What happened is that Netflix went to Level 3
who already had a peering arrangement with Comcast which was built around
normal (roughly) balanced peering.  It had been in place for years before
Netflix signed with Level 3 and worked, and was contracted this way, around
relatively balanced traffic.  Once Netflix started sending most of their
traffic destined to Comcast end user through Level 3 things got out of
balance.  Netflix still has a contract with Cogent (I believe that is the
correct one) or other provider that had previously been handling the bulk
of the Comcast directed traffic, but the Level 3 connection was cheaper for
Netflix.  If anyone actually acted in bad faith it was, IMO, Level 3.

His point was you can't simply change a contract without having both
parties involved.  Level 3 tried to do just that.
