The commodification of information–making news into a product that must be purchased–restricts the egalitarian founding principle of the newspaper. Editor's Weblog reporter Katherine Travers, addressing this issue in a post discussing the future of The Washington Post, asks, "is digital subscription as permissible as charging a couple of dollars now and then for a paper copy?"[58] While subscription fees have long been attached to print newspapers, all other forms of news have traditionally been free.[59] The UK's Daily Mail argues that print revenue is unique because "people pay for the convenience of print in recognition of the special cost of production and delivery of a tangible product and because they purchase it whole."[59] Online news, in comparison has existed as a medium of free dissemination. Poynter digital media fellow Jeff Sonderman outlines the ethical tension created by a paywall.
