There was a point in the development of the internet when we switched, without a lot of discussion at the time or since, from a world of collaboratively-developed, open and decentralized protocols, to a world of private silos. It's like the internet developed to the point of creating HTTP and then that one broke things from there on out — can you think of a single major communications protocol that was created after HTTP and is still in use? Seems like it's pretty hard for open distributed protocols to compete with the convenience of vertical, for-profit sites. If we can ever sort out the problems with cryptocurrencies+smart contracts, one of them might someday provide a path to creating the right set of incentives allow splitting protocol creation, hosting, and maintenance once again. No idea if that will come to pass though.
