My experience with OSM is limited I only contributed a few times to the data in a local city in the Netherlands. I also used the xml data export only a few times for small experiments a long time ago. but from my experience is see the following:
* If many people enjoying or live somewhere they will update it very fast and accurate. Way beyond google and apple will ever have. (If a bench is placed somewhere else on a school campus then it will most likely be update within a few days, from my experience at least)
* Small structures are detectable on air and satellite images but it is really hard to know what kind of structure it is.
* Data from the dutch local governments do, from what I see on OSM, often contain good updates on new buildings. But if something old is changed. (Like a temporary school building is removed then that change is not reflected by a data update from the goverment, and it is often removed by a user after a while) So getting better data from the governments is probably a thing.
* A lot of layers are build on top of OSM. For example if a building is easy to use as a person who uses a wheelchair and if there toilet is wheelchair friendly. My ex-girlfriend was in a wheelchair so I used a app for that a lot. But she never used It. They app was very slow and had a strange UI. So changing the data of custom layer on top of OSM with better tools is hopefully going to be a thing.
* Users use it mostly because they like to contribute. Google has the power to send many people notification questions about places where they have been. OSM does not have this power.
* I would dare to say that OSM is already way more precise then google or apple maps. But users do not always care about that. The big driver for me to keep using google maps is that I often just want to go somewhere, and to go somewhere means that I want to travel by using the train or bus (after covid). In the case i'm in the city I want to know how long it takes to go somewhere by bike or by foot. In the case i'm going to a new city I often want to see how something looks and Google streetview or general images are better then a map. Google prioritizes all that information above having a more accurate map.
So no I do not think it's about getting more people involved. I think it's more about what kind of user does the platform want to have.
