Don't worry. These companies are not stupid. And they are all having a
long record now of contributing to OSM. Sometimes this did not went so
smooth, but they all demonstrated interest in improving the cooperation.
Maybe think of it more as an analogy to a Linux Distribution.
We are the upstream. We have the latest and greatest data. But also
sometimes rough edges or vandalism not yet corrected.
Certainly this raw and unvalidated data is not suitable for all
use-cases. Sometimes you are happy with some slightly older data which
has passed some validation. And that is then a product these companies
can use.
Watch some of the SOTM presentations of the big companies of how they
work with OSM data and their data validation teams. Then it will be
obvious why you often can't directly use OSM source.
Unless you have extremely good ways of automatically merging in your
fixes, it will always better to fix problems upstream. And to my
understanding they are doing that.
And as long as the majority of the data originates from OSM they have a
strong business interest to keep OSM in a good shape.
