So, if I understood it correctly, you're implying that it's totally<br>
fine to hide data source attribution several clicks away or not<br>
attributing at all? And that the attribution on the corners of the map<br>
are only feasible if you're using OSM's tiles?<br>
<br></blockquote><div>OSM has imported sources that are ODbL. The attribution to those sources does not appear on the map, but rather after several clicks (usually first to the copyright page, then the contributors page). If that's not acceptable under ODbL for a map that has multiple data sources, then OSM would be violating others' ODbL licenses.<br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
What I don't understand is the positioning of corporate users of OSM.<br>
Sure, Mapbox has a business model that depends on attribution and even<br>
then you're obliged to follow their terms of use and policies if you<br>
choose their service. How is that different from OSM? Both provide the<br>
same services, you can choose both Mapbox and OSM for tiles or data,<br>
and even then, you are required to follow their licenses and<br>
terms/policies.<br></blockquote><div><br></div><div>
The key difference is between using a service (such as tiles hosted by a company, such as Mapbox), and using open data that originated with but *is not hosted* by an entity. I agree that if someone were to use OSM tiles hosted by OSM, then attribution should be visible in the corner at all times. <br></div></div></div>
