Which is not surprising, as those two have very different priorities.
- OSM want's a detailed and reliable map.
- Google maps tries to either sell your data to clients, or make you buy from them.
Their business data is their priority for maps. You can see that clearly when you look at location history changes over past decade or so. It used to be actual user location history and it was glorious. Now it's "near what businesses you were more or less, help us rate them".
It's a great moment to again remind about existence of low-friction tools that you can use to add business data (among others) to OSM, like StreetComplete app, available on F-droid and Google Play :)

In my region OSM business data starts to be on par with google, better (more up to date) sometimes.
