When Apple started designing their unibody Macbooks, they needed to put a hole in the aluminium for the power LED. There was only one company in the world with the equipment to make those (multiple-of-nanometers-wide) holes.
Simple solution: Apple just bought the whole company. Voila, now Apple can cost-effectively produce those holes with one less renewable contract.
