The distinction gets at something interesting though, and it's a weird intermingling of culture and politics. I think a truck as owned by a consumer, and as an American would understand the word, is, at least in part, a lifestyle statement derived from maybe overprovisioning on the horsepower. Such a lifestyle statement in Germany seems to be perfectly socially acceptable when it ties in with luxury and doing your "civic duty" by buying German, but it clearly ruffles feathers and meets with political headwind when it ties in with the culture and financial constraint of the "commoner".
In my experience the resistance seems to come from the sense of “waste” that comes from buying a specialized vehicle. Anecdotally the folks I talk to (all blue-collar “commoners”) are overly focused on buying the eierlegende Wollmilchsau[0] vehicle. They view specialized vehicles, especially luxury-priced specialized vehicles, as an unnecessary waste.
Does this relate with your experience? It sounds like your perspective is broader than mine and more informed.
Edit: oof two downvotes for trying to have a conversation and expand my understanding of a culture. Vielen dank.

For what it’s worth, that horsepower is billed for towing.
