Because the underlying data is CC-by-SA some people think this extends
to map tiles as well, and that the copyright on the data exceeds any
T&C, I'm not a lawyer etc etc etc, nor am I expressing an opinion.

It has also been stated that the ODBL clarifies this issue and the
license is specific to the data only, and doesn't extend to derivative
products from the data.
