I can’t find a official statement from GOG with that content, only statements where they say that it was a error both in the internal processes, with not waiting for the responses of all internationale, especially in this case the german, teams before sending the newsletter and with checking if the runes could be problematic in some fonts.
The runes themself are both from the intended design and from the connected meaning and symbolism unproblematic, yes they can look problematic in the wrong fonts but that is more a problem of font design then of ill intent.

Well the games name is “End of the Sun” and it is a Slavic game, so using a slavic sun rune is not that extremely far fetched. Why using it double, which lead to the SS appearance, i``s another question and it was dumb at least. But I still don’t see ill intent, when something like that happens once I am fair enough to accept that people can do things in error. I still try to see the good in people
