Is it just me, or is this awful logic?

Really, we DO NOT WANT every site that considers itself to have "mission
critical needs" to be multihomed.  This would lead to an explosion in the
size of the routing table.

When two "Tier 1 Wannabes" get into a peering dispute and start
deliberately breaking reachability, this is an artifically-generated

It certainly strikes me that someone here isn't making "best-effort"
attempts to supply Internet access.  One would wish that the customers
of that guilty party have contracts which require "best-effort" attempts
to provide Internet access, which would mean that a peering spat that
results in visible traffic failures ought to open the door for customers
to migrate ... elsewhere.  Of course, while that might be fair, it isn't
compatible with the real world.
