Maybe they'll put a list of repeated identities in their next rootkit they ship with their laptops and when it detects someone associated with an identity it will signal the battery to explode...

Ironically, they'll be guilty of the crime "battery".

Anyway, I think we all wish companies would take their revenge in the form of actual violence so that they would actually get in trouble, but they are smarter than that. Emotional pain hurts more than physical pain.

(Based on what they've currently said, which I wouldn't trust, personally)

They aren't looking for identifying information. They are looking for location information to prove that San Francisco is an appropriate venu. IP addresses will give them pretty strong location evidence, regardless of who was behind that IP.
