As much as I am disappointed on how EA is managing UO, you cannot really blame the fact that UO is not easily expandable to UO mismanagement. UO and EVE have fundamentally different architectures. The one of EVE allows non limited expansion, it only imposes (severe) limits on the people that can stay in a single system (as jita shows). UO architecture is much less flexible, and only part of it depends on wrong design choices. The differences in the gameplay really make the EVE choice much more feasible for EVE than for UO.
