> a sustained DDoS attack will just make your host drop you

I'd love to see someone suing the host for damages. The contract binds them as much as it binds you.

Sounds like a good way to have your next gaming rig financed.

I'm pretty sure in every webhost terms of service I've ever read they leave language in to kick you out if you are degrading the service for others. Turns out a prolonged DDoS attack is degrading the service for others. The bigger cloud providers are drastically less likely to drop you but now you're paying a premium on hosting.
