I think it might even be inaccurate to describe something as "the open street map network", because "the" implies there is only one network of street maps that are open. Alternatives like "All paths were map-matched to the street map network provided by ..." or "All paths were map-matched to an open street map, specifically ..." would probably be more correct if the goal is to avoid the brand name.
I see no reason to discourage brand names if their products are specifically directly to the research in question. Avoiding brands is a lot easier in other fields of science, but even there attributing data sources should be acceptable (or even required).
It looks to me like the this is the result of sloppiness or an overzealous editor.

The algorithm used to compute shortest-distance is entirely irrelevant, unless there's some doubt about the correctness of the algorithm!

OpenStreetMap. Weird sloppiness there.
