Wow, pretentious much. The Wayback machine is an interesting passing curiosity that with great luck sometimes saves a webpage that isn't completely broken. The average person has never heard of its existence. Sure it's fun looking at how web pages used to look like and laugh at terrible designs but it's not exactly part of anyone's real workflow and surely violates right to delete and a bunch of other copyright laws.
You've stolen and rehosted the world's content and now you're surprised people are suing you? Do these people hear themselves? Did they not see pirating sites being fought tooth and nail in the past decades? I'm frankly surprised that the FBI hasn't sized their domains years ago.
