This is heavily misleading, but still very informative as the title sounds like it is a problem with the German government, but it is not.

America penalising money transfers to Cuba - which most likely causes the issue - is a problem banks encounter in the entire world not just Germany. France’s BNP Paribas paid 9 billion penalty, Commerzbank “only” millions. Therefore, GLS and other banks act overcauciously.

This has nothing to do with the German government.
