They're not trying to seem foreign, it's what happens when a foreign culture starts spreading. In that sense McDonald's has certainly played its part, but mostly because a lot of people use rules like these somewhat subconsciously. E.g. this > The Deppenapostroph is not to be confused with the English greengrocer’s apostrophe, when an apostrophe before an ‘s’ is mistakenly used to form the plural of a noun (“a kilo of potato’s”) This also happens in German these days even though in this context it makes almost no sense. And nobody is trying to copy McDonald's here.
