It's clear Jay Michaelson is a Daily Beast columnist—specifically, he's their legal affairs columnist. David Rothkopf might be more of a guest columnist, judging by his author page. So I guess Michaelson's POV is the more "official" one?
Here is what The Daily Beast says on its "Code of Ethics and Standards" page regarding Opinion pieces:
Opinion: The Daily Beast features sharp opinion as well as original reporting. Our columnists run the gamut between liberal and libertarian. We value ideological diversity and substantive debate. Opinion pieces do not necessarily represent the editorial perspective of The Daily Beast. Our readers are reminded that there is no right not to be offended.
