If you police it it’s not a cultural thing. If it was just a cultural thing than we could just let the * slowly die out. But banning language hinders progress. And I’m sorry, but the German language is constantly shifting and changing. There have even been multiple planned changes that went pretty well in recent history. Using English words might have been a big change back then, but now it’s really common. The first terms for mobile were things like “Taschentelefon” (pocket telephone), “drahtloses Telephone” (wireles telephone) or the one that is still in use “Mobiltelefon” (mobile phone). None of these seem outlandish to me.
If a battle can not be won do not fight it.
