In my opinion this is because big companies do not want change. They are already big companies. They already won. They care more about understanding how they won / are winning so that they can perpetuate it and extract small percentage increases each quarter. Big things move slow. If you try and move part of them too fast they might break away and potentially endanger the remaining whole.
