Yes, if Ford believes that their customer's independent decisions about parts and service could lead them down a path that makes you more sour about Ford as a brand and degrade/ruin your relationship with Ford as a consumer. This could easily happen in the wild west of unauthorized parts and service. I think the laws are wrong in this case and compromises a company's ability to maintain that brand relationship. Are there undesirable consequences to this? Yes, but they can be sorted out one-by-one.
