I think this well documents the history, how first OSS and then SaaS got so major things in especially enterprise software. At the same time I don't think this gives us any clear pointers on the future, that is still on our hands to shape. Although I feel the perspective is one of larger, well functioning IT depts where you actually have choices and could look at the economics. In practice I think many real world IT depts don't have such luxury and are instead barely struggling by, grasping anything that will help them short-term, long-term economics be damned. I would love to see a world where IT depts would be maintaing (truly owning) large catalogue of software in-house, but that doesn't seem realistic at all.
