Long ago IBM split itself in to 7 internal subdivisions that could to a certain extent compete. At the time all of IBM's equipment ran on chips made by IBM for IBM products. The florida area sub-unit which didn't actually make any computers, put one together from intel chips. It was dubbed the PC. The OS was contracted out to some kids from Seattle.
Sony's products division is constantly at war with it's content division, leading to the constant hedging on content protection that defeats their products by using non-standard formats with DRM.
Perhaps Samsung, which is really a humungously diverse set of industries, just has different competing segments within itself. Each has a strategy that is aimed at competing with the other divisions strategy but has to be distinctly different due to the internal politics, just like IBM's PC did.
Its not s strategy to do everything, that's just the result.
