Of course they are. WL is doing exactly what the press is supposed to do. Disseminating information to keep governments in check. That is the exact task for which the press exists, and why the press is guaranteed freedom in the first amendment. To claim that WL is not part of the press is to fundamentally misunderstand the purpose of a free press.
Look at it this way, publishing Watergate was free press. It was the uncovering of a criminal act by an elected official. That's exactly what WL is doing.
