The business model of these companies seems in question long term given that they rely heavily on location data “opted in” from users that honestly probably didn’t realize they “opted in” to share their data for such uses. As more efforts continue (by Apple, Firefox and others) to crack down on that sort of thing the proportion of reality represented by the data such companies hope to sell gets smaller and smaller. It’s increasingly not “people shop here” but “people with bad privacy settings on their device shop here.”
