Agreed.

The arguement here (if there is one) is that their is a demand in the
marketplace for multihoming to different providers and what is the
best way to treat these customers.  Sprint's filtering is a good
arguement for having multiple Sprint connections or non at all.  The
customer that is multihomed to Sprint and a different provider,
however, is still paying Sprint to move their bits around even if
their Sprint connection goes down.

I support all incentives to reduce the number of multihomed customers.

And not plugging their routers into outlets on light switches would
also help.
