I have to applaud LH and Germanwings for their very sensitive handling of the relatives. I read only positive reports about their approach to all of this. Compare this to Malaysia's handling or AF they are doing a really good job. Same is true for the locals in France, who are standing up to the difficult task brought upon them.
Lufthansa had a prepared 800 pages document for this with precise instructions how to handle the issue and when with completed wordings. This included the greying of the logos and banners, the absence of LH logos during press conferences and dressing, etc. This document has been partially published today by German newspaper Bild and others.
They do a good job. Because they were professionally prepared to stage a perfect media handling.
