It's not about politic, it's about a company, Royal Air Maroc, that has been completely dedicated to the american manufacturer for many years. RAM was one of the first to order the B-737 NGX and is still flying a B-747-400. The error has been fixed, yesterday, in PMDG liveries download page...
RAM is also expected to be the first airline in Africa to operate the Boeing B-787 Dreamliner.
You can also find a JET4YOU livery on AVSIM by typing Jet4you NG.
Royal Air Maroc can now be downloaded on PMDG website
