Everyone is also okay with driving combustion vehicles for the time being, even while realizing that it might not be the cleanest option. Supporting Google similarly feels dirty when necessary, but yes it's the norm.

For some things like traffic info, there also just isn't much of an alternative that works in most of the world with one simple thing to implement. There are things where OSM or TomTom or so just can't compete because it requires tracking half a billion people's locations in real time. Or showing up with your opening hours on Google's search monopoly by existing as a POI on TomTom or OSM will also just never happen, whereas existing as a POI on Google Maps is enough (using dominance in one market to influence another market). I know "everyone" is fine with using these products, but that's not why nerds get enthusiastic about seeing OSM in different places :)
