Tim Cook with iPhone
Apple CEO Tim Cook is taking the fight over its control of the App Store to Europe.
  • Courts and regulators around the world are trying to get Apple to open up its App Store.
  • Apple hates that idea, so it's trying to blunt those efforts every way it can.
  • The newest fight is in the European Union over "sideloading" apps.

European regulators say Apple needs to open up its App Store, and a new law that goes into effect in March is supposed to make that happen.

Apple's response?
