I'm a little confused; who do you think is supposed to solve the problem of a clear readable transit map other than a designer? Also what is this "old map that many people were just fine with for decades"? The BVG revises their map, what, yearly? They had to cope with a rather radical set of revisions a couple of decades ago. And more recently with the opening of the new Hauptbahnhof the entire transit system of Berlin has rotated around a new axis.
