Great read: Structuring a Decentralized World.
Openness also has subtler, yet more profound, benefits than pure cost-cutting. Whenever there is any new conceivable space, virtual or real, that can be owned, there is usually a frenzied rat race to own it. People love to copyright or patent everything under the sun (see: Amazon.com’s 1-click court case). To maintain this ownership, the owners require strong enforcement. Often, governments acts as a proxy for that enforcement. This inevitably results in restrictions for users.
Companies are beginning to realize the futility of placing restrictions on users with schemes like DRM. These restrictions are always reverse engineered and bypassed. Thus, the companies that use them do not prevent piracy, and the companies that do not use them are applauded by their customers for a hassle-free experience.
