That article is clearly wrong. Apple isn't headquartered in Germany, it's not building phones or computers or software in Germany. It only owes Germany minimal income taxes, while it pays huge amounts of VAT, and employment taxes for store employees.

It's like saying Porsche should pay US income taxes on cars it builds in Germany because it sells them in the US. Porsche pays sales taxes, import duties, etc, etc, everything it requires. It's profits on it's U.S. marketing and distribution operations are minimal, so it should pay minimal US corporate income tax.
