Apple’s problems in Europe look to be getting worse, not better. Following on the heels of France’s legislative push for DRM interoperability comes word that Denmark is thinking along the same lines. Reportedly, Maersk and the country’s largest telecommunications company, TDC, are speaking out in favor of such interoperability. Maersk and TDC are not only two of largest companies in Denmark, but they are amongst the largest and most powerful in Europe. Both also operate online music ventures.
