Leaflet has a plugin that can fetch Bing Maps tiles. However, I see in the Bing Maps terms of use the following prohibition:
8.2 d) Use Content, including geocodes, other than via an authenticated call to the Services and/or in conjunction with a Bing Map.
Would this not make any use of the leaflet plugin a violation of the terms of use? Are tiles specifically different from other Bing data? Or is there a specific exemption that has been offered to Leaflet?
Further, if other services are used, e.g. geocoding with OpenStreetMap data, is that a breach of the above?
