It wasn’t, this is their second apology! From the first (with added emphasis):

What was displayed in several devices as doppelrune is out of our control. ᛋ was displayed as ϟ on several devices (might display for you differently here as well just letting you know). We should pay more attention to checking it on a different systems and devices. I also recognize that placing two such runes next to each other could create an unfortunate association with symbols used by the Nazi regime. This was noticed before distribution, and out of respect for local sensitivities, the material was not sent to the German community.
