These companies arent still related to the past? What about when Siemens proudly announced their new vacuum cleaner the Zyklon? Oops they never knew about the connection they claimed. Even though they used slave labor by the Holocaust.
Also you can’t compare not using italian products since they are connected to Rome of past. I mean seriously some of our grandparents have either survived or been murdered in the Holocaust. On the other hand lahavdil elef, for the Germans some of their grandparents were the ones who killed us. And don’t kid yourselves many Germans passionately hate Yidden.
It’s true we can’t avoid everything. Even jpmorgan Chase froze french Jewish bank accounts even before they were asked to do s by Germany. And the list goes on and on. But a Volkswagen or a mercedez surely is easier to avoid.
It’s also true that most of the world hates us. Even Samsung had an anti semitic fit with one of their Jewish investor/partner. Europe hates us and even many Americans do. But it still doesn’t mean we should buy German. That was a direct hit. And most of those companies either originated or flourished in that time on our backs. Look into it even orange fanta was known as a Nazi y”m drink since they ran out of coca cola ingredients. And coke recently aired a banned commercial in German accent which said, just like the good old times.
