If the desire is so strong to make discourse open and unencumbered by individual corporate walls, then this one article could have been placed up outside the paywall. To say, "I think we need an open public forum" on a medium as open and public as the WWW and then to restrict it behind az paywall kind of misses the point of the article itself. It is within a walled garden arguing for an alternative to walled gardens when the party publishing it is the one controlling the walls in this case.
