Not sure the counter example of Apple stands; they have a specific goal: be in full control of the whole technological stack for their products. They don't design processors and sell them like Qualcomm; they just do whatever is necessary for their product line.

A conglomerate like HP and Samsung often has little to no cross-pollination between divisions. Obviously the semiconductor part of Samsung can benefit the whole business, but the intersection between TV and dishwasher is probably zero, even at marketing level (they have totally different marketing and sales departments).
