sorry but that is simply not true... I think there are areas where it can be, probably those more remote, or where there are less contributors but at least in western europe, the map is built and maintained by individuals like me. Maybe helped with external datas but still carefully handpicked and integrated by individuals

The statement is at least partly true. Nearly all big corporations and many smaller ones have people on the payroll contributing to OSM. And there are entire countries where paid / commercial editing makes up the majority of contributions to OSM. See this post from last year that breaks it down: https://www.openstreetmap.org/user/Jennings%20Anderson/diary....

Hang on... I can get paid to edit OSM instead of just doing it for fun? Where do we find those jobs?

This is typically offered as minimum wage job in poor countries.

For example one company caused noticeable damage as UK was mapped by people from Belarus who were unaware about many local intricacies.
