I guess the wording is incorrect in that misinfo, but Steam has region blocks on all adults-only games in Germany. Adults-only games are legal in Germany, but it requires stronger age verification than that of Steam's. I guess Steam just went for the simplest no hassle solution and just region blocked those games.
So yeah, it's not like Germany has F&H on blacklist or anything. But when people say it's banned, I doubt they think they have problems with F&H especially. It's just an umbrella term for the issue.
