 The critics pointed out that the entire lawsuit depended on a short, one-week-long period where Cragslist's terms of use required that users assign Craigslist the exclusive copyright of any posted content.While some users may be happy to have other companies use their classified ads, another reaction was that there may also be users who do not want it.Craigslist would be under similar criticism if it had allowed the sharing and violated these users' privacy expectations.
