No, I can't make that leap. Firebombing? I don't condone DDOS, but that's just crazy. The moment people can die (without citing some kind of really strange examples) from DDOS, I will reconsider but come on.

Arson is a serious felony because people are often killed by it, inhabitants and/or firefighters.

A DDoS is akin to blocking the entry of customers to a retail establishment.
