I agree, but people on HN don't seem to care about those as much as US startups. Plus who is worried about car dealerships going under just because they can't pass on your data to some scummy vendor? (Also, some countries have laws close the the GDPR already, where this wouldn't fly.)

Having said that, shunning one car dealership is way easier than trying to stop Facebook or Google slurping your data, even with ad blockers et al.
