Please note that there was no analogy in my original comment. I was merely summing up the OP's argument. Additionally, as someone who has plans to write a craigslist-centric app, and took the time to read the TOS, I find it idiotic for a developer to charge ahead with creating an app/site without either understanding the terms, or obeying them.
What's more is that you are arguing against the notion that whoever creates the content (or own's the content) has the right to decide what gets done with that content. And no matter how much you dislike what they are doing with their content (ie. not creating a shiny interface to access said content), that does NOT give you the right to use that content without permission. It is my understanding that craigslist often gives out permissions to use it's content, and it would appear as though this company didn't bother to secure that permission.
