Those agreements are made (or not) by the entity running the network, for
its own reasons.  It may enter into contracts (e.g., for transit), and may
influence the terms.  In any contract, there is some form of
consideration, which the parties like or they do not contract.

Sure, fat-fingering happens.  It's quite different than state-mandated
carriage of routes originated from elsewhere, which was the message to
which I was responding.

An RPKI would be helpful, though I have some technical concerns about it.
