Wow, that is quite a way to open an article! Isn't journalism supposed to be slightly more neutral than that. I understand that most of us (myself included) are quite against copyrighting, DRM and closed source etc. but let's not harshly rebuke a company with 30 employees [1]. Simply put, copyright is a contract between the society and an individual that encourages the individual to create, innovate and be artistic. Craigslist did things that they thought were right to protect their users' and their own interests. They found a market. Padmapper used their data. Courts said it is ok to do so since they didn't the copyright to begin with. Fine, let's move on.
No reason to write such a bitter sounding article peppered with "Let this be a lesson to all tech companies", "hopefully this will discourage craigslist", and "sledgehammer to scare innovators". tsk. tsk. Forbes.
