I'm also not sure that I would say that there are MANY anglicisms used, but granted there are a few. There is in a lot of other languages as well though, and we use terms in the English language that are French, Spanish and Italian just granted, maybe not as much. Along with the points raised above which I agree with, Italian also isn't a language that is globally spoken like English, Spanish or even German these days is, so maybe that's another reason why other terms are used as it helps to make a point as well as get it across to others who maybe aren't so familiar with the Italian language.
