Yes, German dialects can vary greatly for example here’s the same sentence “I have an apple.” in different German dialects:
Standard German:
“Ich habe einen Apfel.”
Northern German / Platt:
“Ik hab en Appel.”
Middle German / Saxonian:
" 'sch’habm Abbl." ( 'sch is pronounced like sh)
Southern German / Bavarian & Austrian:
“I hob an Opfü.” (I is pronounced like the single letter E)
The Southern Germans are the ones with the Schwarzenegger accent.
Positive news: at least Germany will reject it, let’s hope more members follow their lead
