I don't think that article is necessarily wrong. You can have natural monopolies that switch companies, but still remain monopolies (look at Apple's early 80s success that was completely squashed by DOS/Windows). Everyone migrated to Facebook and ditched myspace. It doesn't really compete with anyone now. Facebook seemed to have learned from myspace's mistakes and have been successful for a decade now. I think a shift to another social media platform is just not in the cards, at least for the forseeable future.
