An effective targeted ad platform is also expensive to develop and keep current.
They either build something as effective and invasive as what Google and Meta have, and prioritise ad revenue as much as those companies do.
Or they stay closer to the ineffective ad network they already have in News, App Store, etc, neither putting their money where their cultural mouth is nor becoming an ad revenue behemoth.
Presumably you don't have to do much targeting with Maps.
If I do a search for coffee shops, it doesn't take much targeting to figure out I'm interested in coffee shops. Same with pizza or grocery store or gas station.
For Maps search results, I expect the revenue will be plenty effective without having to be "invasive" at all.
