A criticism of that point of view is often that good journalism needs the money to send journalists into the field. I think that point of view forgets what journalists are by function - a way to connect people to other people; a technical problem. If we can make sure that anyone who wants to be heard can speak somewhere where everyone who wants to hear them can, we're done. The network effects implied by that will probably shift through a lot of stable configurations in future, but none of them will be effected at all by simple distribution monopolies. Computer networking and mobile are changing everything.
Product journalism is even newer than commercial music, and will also end up in the history books as a relic of the 500 year period on history where the kinks in the mass reproduction and distribution of words, images, and sounds were being worked out. Then we move on to touch:)
