I think all discussions about contemporary journalism are somewhat problematic because news organizations are profit making businesses that also convey the impression that they are important civic institutions that live up to a variety of ethical standards and norms of journalistic responsibility. The thing is, you just have to be a significantly large and important enough organization and you can effectively declare that you embrace these norms without ever being entirely clear about what they are or bothering to try to live up to them. So Politico becomes a serious responsible news outlet simply because it says it is.
Greed is a defense, but it doesn't mean the rest of us have to treat them with any respect.
