In the United States, reverse engineering is entirely lawful. It is even made explicitly clear in the DMCA that reverse engineering is allowed. Which part are you specifically worried the most about?
> With this information, (if I'm not wrong) it wouldn't take long to simply DDoS Siri...
This is just scaremongering. Knowing an IP address is enough to DDoS a server. Are you suggesting that it's somehow unethical to independently publish the location of a publicly-available server? Are you also going to indict the DNS server that gave it to them?
> Or port Siri to Android (effectively stealing IP).
Theft relates to physical property. I'm not sure what would be stolen here as Apple still controls the Siri server and requires a unique iPhone 4S ID to be used. Again, though, reverse engineering for the purpose of interoperability is legal in the United States. There's no way to frame this as stealing.

This is a red herring. Your proposed situation suggest a security vulnerability of some kind wherein Dropbox hypothetically allowed someone access without paying. No such vulnerability to Siri was found; all requests to the Siri server were made using a valid phone id and returned valid, official responses.
The only thing that's unclear to me is if the anti-circumvention portion of the DMCA extends to technology used but not created by the author e.g. Apple did not create SSL but they use it to secure transmission - does this make spoofing an SSL certificate an instance where the DMCA's anti-circumvention law would come into play?
