Roblimo writes "Bing and Mapquest both use output from OpenStreetMap.org. Mapquest supports the project with money for equipment and access to the code they've written to integrate OSM's work with their display. Bing? They just take from the project and do nothing for it in return. This may be okay in a legal sense, but it is a seriously nekulturny way to behave. Even so, having Microsoft's Bing as a reference might help the project's founder make money. They've put a lot of work into this project, and it's doing a lot of people a lot of good, so they certainly deserve some sort of payback, either direct or indirect. They have a few ideas about how they might legitimately earn a few bucks from their project while remaining free software purists. Do you have any ideas, yourself, about how they might turn a few bucks from OSM?"
