The underlying problem is how this essay uses the word "own", which is as dictation. In almost any context, ownership should primarily about responsibility for the outcome, with the minimum authority necessary to coordinate work towards that outcome. People who are good at owning things will push most decisions to people closer to each sub-problem, while giving an overall framework that keeps everyone rowing in the same direction. For Product, that manifests as a roadmap with high level prioritization, but plenty of room for engineers to tweak scope or ordering to take on targets of opportunity.
