Hierarchy and centralization are ways to manage complexity and stay efficient as the article correctly points out but one additional point, topological pressures aside is also division of labour and specialization.
Sufficiently large systems benefit more and more from specialization, the emergence of content delivery networks on top of the more generic internet is an example. As the types of content we consume are getting more and more sophisticated, bandwidth heavy and capital intensive, specialized infrastructure and distribution pays off more and more.
For that reason peertube and other alternatives are pretty much structurally doomed. They'll never compete or be as economical as services and infrastructure optimized for that task.
