How Can We Create a Public Interest Technology Without the Advertising?

We have allowed ourselves to kind of build infor structures that are so much built on private enterprise or public at partnerships, it's really hard for us to imagine how things could have been designed otherwise. In the book there's also a discussion about how we shouldn't expect advertising companies such as like google or facebook to act like public knowledge bases. So i think part of our inability to imagine what a public infer structure would look like is in part because we have been trained for decades, if not centuries, to think that all the most ambitious planning has to come from the corporate world.
