They are doing exactly what they should be doing. They cannot allow politicians in an insignificant country to dictate how they run their store worldwide. If they want special treatment they will need to put up the effort to do so. Otherwise deactivate their store in the country and move one.

If European countries or even the US make the App Store unprofitable it become a liability instead of a profitable asset. They will move on to a different platform.
