Spent millions gathering? Two basic problems with that mindset. First, spending money to assemble a database of public facts does not magically give you a right to protect your investment in an uncopyrightable asset. Second, I don't know what millions you are talking about since craiglist's only asset is the users, and the users are just a result of tremendous network effects. They had a great idea and got very lucky, but gathering their massive userbase had nothing to do with spending money.
Could someone explain what they disagree with? Do you disagree that databases of public facts are not copyrightable? With the idea that craigslist's investment in their system is irrelevant compared to the value of their userbase? With the idea that craigslist's main success is just being lucky?
