The startups who are Craigslist bashing just have a vested interest in getting access to Craigslist content without any ToS. It is more like demanding that a property open up because there is gold on it and they are demanding that it be made available to them because they can serve gold to the market better than the land owner. From what I am reading though, the businesses are offering nothing in the way of compensation and this is more of a property grab.
