That's kind of the point - English imported them from German (or, rather, just uses German words). English does that all the time. Same with French - rendezvous, cachet (don't confuse with cache :), passé, etc. So French speakers shouldn't feel bad for taking words from English - that happens all the time, just this time English is more popular so other languages take from it. Before that it was German and French, and in 100 years maybe it will be Mandarin, who knows.
