The gesture in question being this:
Now to Americans this looks like the "Rosie the Riveter" pose but it turns out that in some European countries this pose is called the Bras d'honneur , a gesture that means the same thing as "fuck you" or "up yours."
Basically a case of including something that's considered fine to people in some countries but considered "not fine" in others. Reminds me of how Left 4 Dead 2 had to have its boxart changed in the UK because the "sticking up two fingers on a backward facing hand" gesture, seen as perfectly fine in most countries, is actually a way to say "fuck you" in the UK.
