You're mistaken as the links you provided indicate. They are about blurring peoples houses on Street View as they are seen from public streets. Completely unnecessary and inconsistent with general rule of Panoramafreiheit.
"in Germany the permission applies only if the image was taken from public ground, and without any further utilities such as ladders, lifting platforms, airplanes etc.". So the law grants different permissions depending how tall you are.
Mind you, this is copyright law. Might privacy be a separate matter?
