I think that phrase ought to be retired simply because even if you are paying money you often still are “the product.”
1. if you don't have leverage with your vendors, they will not bend over backwards for you
2. companies are not incentivized to respond to complaints with no revenue at risk (e.g. you're going to use youtube anyway)
The way I understand it, usually either the dealership, the software they take your information in, or both typically sell off your data after the sale.
Also I get calls and letters from places asking to buy a vehicle I haven't owned since 2018 regularly.
