It's arguing that corporations are contributing data to OSM, but that this somehow... changes the proportion of what kinds of things OSM covers? That traditional users have added "hyperlocal features, such as a neighborhood bench or informal walking path" while coporations are adding "roads, buildings, and all other points of interest" and "a particular emphasis on improving road data".
How is this anything but good? As long as data is correct, the more data the better -- proportions are meaningless. Buildings and roads aren't taking away from benches and paths. And I'm pretty sure buildings and roads are benefiting all users anyways, no matter who contributes them.
I'm utterly baffled by what logic the author imagines this is a bad thing. The data is open, so it's not like corporations are winding up with exclusive ownership of anything.
So what's the problem...?
