I sense that the EU likes to randomly boss around U.S. corporations. Remember this BS?
That story was riddled with such misinformation it was ridiculous. People thought it was the European Union itself or European Commission that stopped sales of the Mac Pro.
It never was. In fact, it had nothing to do with the EU at all.
It was the International Electrotechnical Commission (IEC), a non-governmental international standards body, that issued the 2nd amendment to regulation IEC 60950-1. (This can be easily recognised by any observant reader within a split second by the fact that European Union's Regulations have a different naming scheme, such as
"Regulation (EU) No 1151/2012").
Through the Dresden Agreement between the IEC and the European Committee for Electrotechnical Standardization (CENELEC), European countries adopt international standards avoid double work.
CENELEC operates independently from the EU.
Instead I'd put the blame on Apple. They probably didn't want to waste time, money or energy to fix the fans on the Mac Pro since they were working on a new model that was in alignment with the new IEC regulation.
