If you design your dedicated map handling system in such a way that it is impossible to add and display proper attribution when adding a new map source manually, even if you wanted to, that application is clearly violating any attribution licence.
Interesting. By the same logic, if I design a map application that lets the user input their own tiles URLs *and* lets them input an attribution string to go with it, then the user would be in violation of the license if he adds the tile URL but not the attribution? Hardly believable.
The attribution requirement of CC-BY-SA is triggered if you distribute (publicly perform etc.etc.) the tiles. The *author* of the software doesn't distribute or publicly perform any tiles, he just makes a piece of software available. The *user* of the software instructs the application to retrieve and display the tiles, but only for his own consumption and not for distribution or public performance, so the user doesn't have to add attribution either.
I don't want to condone what this "Locus" guy does, and certainly inciting users to violate our usage policy (and using faked headers etc.) is a bad thing. But I cannot see a CC-BY-SA violation.
