The incentive simply isn’t their for anyone when there is already a perfectly working solution—as much as I hate to say—from Google

So you enjoy corporate oversight and ads? or at least they don't bother you enough to seek alternatives?. It's not political, I am spelling out what you seem to be trying to avoid saying.

I wish OSM and the maps & navigation apps using it were more popular and better but they aren’t simply because they don’t have dedicated teams.

But you don't wish it enough to contribute in any way...

Google Maps also get contributions from the community (which is much larger than OSM). So google benefits from volunteer contributions as well as their own teams mapping stuff around the world which OSM can never match. It isn’t something like Search, Drive or Photos that can be replaced by a community driven FOSS alternative. It requires huge funding.

I think you are just doubling down on this to convince yourself that it is not that you are being selfish here, you are just being smart by not choosing a losing battle you made up in your head.
