Hopefully, the more a business pays for an ad, the higher it climbs on the listings top ladder is not a feature of the Maps ad program. My preference for category searches (coffeeshops, restaurants, etc.) has always been to have the business closest in location to appear at the top. Others might prefer review rating or “fastest route” to be the default which would be fine.
At the least I would expect a new Maps setting that allows me to set a listing order priority. But I know, the TC Apple would not ad such choice because that would give me control over being a customer v. being a product.
