If I de-peer them, I pay my upstream to carry the
attack traffic.

If I maintain peering with them, the attack traffic is free.

It would seem the economics work the other way around.

It would be more cost effective for me to identify the largest sources
of attacks, and reach out to directly peer with them, to avoid paying
an upstream to carry the traffic, if I'm going to end up throwing it
away anyhow.
