This was intended as trenchant commentary on Google's book-scanning project, a generally laudable effort to scan and index all the books ever published, including huge dark-matter of books that are out-of-print with no clear rightsholders.
Pat Schroeder and the American Association of Publishers have sued Google over this, saying that Google shouldn't be allowed to index these out-of-print books (the majority of books published) unless they take on the Sisyphean task of figuring out who controls the copyright to all of them and then get permission to make an index.
Google makes indexes of every page on the Internet without ascertaining who their copyright belongs to, without asking permission. If your page is on the public Internet, Google will index it. The publishers argue that books shouldn't be indexable without explicit permission.
Larry Lessig has posted a great rebuttal to the idea that stealing laptops is the moral equivalent of indexing books -- a must-read if you want to understand exactly why Charkin's stunt was so mind-numbingly wrong-headed.
(3) If the computer was not sitting at a market booth, but instead was in a trash dump (like, for example, the publishers out of print book list), or on a field, lost to everyone, then that fits the category of property that Google is dealing with. But again, Google doesn’t take possession of the property in any way that interferes with anyone else taking possession of the property. The publisher, for example, is perfectly free to decide to publish the book again. Instead, in this case, what Google does is more like posting an advertisement — “lost computer, here it is, is it yours?”Link(4) Or again, imagine the computer was left after the conference. No easy way to identify who the owner was. No number to call. In that case, what would the “head honcho’s,” or anyone’s rights be? Well depending upon local law, the basic rule is finders keepers, loser weepers. There might be an obligation to advertise. There might be an obligation to turn the property over to some entity that holds it for some period of time. But after that time, the property would go to the “head honcho” — totally free of any obligation to Google. Compare copyright law: where the property can be lost for almost a century, and no one (according to the publishers at least) has any right to do anything with it. Once an orphan, the law of copyright says, you must be an orphan. No one is permitted to even help advertise your status through a technique like search engine.
(5) Or again, imagine the computer was a bank account in New York. And imagine, the bank lost track of the owner of the account. After 5 years, the money is forfeited to the state. Compare copyright: in New York state, a sound recording could be 100 years old, but no one has any freedom with respect to that sound recording unless the copyright owner can be discovered.
