So a hacked cable modem would only be able to listen in to one side of the conversation: the side that you receive.
Anyway, the internet is fundamentally insecure: why worry about the last few hundred yards on cable being unencrypted when the remaining thousands of miles are unencrypted, and capable of being two-way eavesdropped?
Sending information on the internet is like writing a postcard: the postman can read it.
