Of course the advertisers themselves want nothing more than for all of us to encounter their offerings, to “engage” and “interact” with them. We have known for years that culture can be a commodity even when you don’t have to pay for it outright. Those who would protect the cultural commons must see that the challenge is not only copyright, but those who own the platforms and channels through which culture is increasingly shared. On their watch, the cultural commons has become little more than a radically discounted shopping mall, a consumers’ paradise of free entertainment propped up by advertising. What’s being hoarded now are the means of delivery, the channels through which the economic value of culture is realized. The commons can be commodified without being enclosed outright.
