So, VW as a brand has origins there, but there's little other continuity. It's a fairly different situation.

Same for Ford in the US, right?

I think people are missing the joke here (notice the italicised 'are').

Indeed,"formerly" carries real weight. It's one thing to have car company with highly distributed ownership that was once Nazi aligned the better part of a century ago, and an entirely different thing to today have a personal piggy bank company for a billionaire Nazi active in global politics.

If a VW exec throws a Hitler salute in public, they will no longer have a job the next day.

When Musk does it, he gets a trillion-dollar pay package.

So no, there's no comparison to be drawn here.

Long ago Nazi vs currently another brainfart away from invading
