OSM Bright cartography copyright claim on Wikipedia Maps #45

Hi everybody from Kartotherian / Wikipedia project,

Please read: https://github.com/osm2vectortiles/osm2vectortiles/issues/387

There may be implications for your vector tiles defined in this repository.

WM is diverging from the MB Streets schema, but the origin of the tm2source is with a clone of MB streets and everything derives from it. If Mapbox's claim is valid, I think the source needs to be restarted from scratch.

@pnorman the SQL of this project were written by @MaxSem, independent of Mapbox. We did follow the styling guidelines set up by MB, but we have diverged since then. I don't think we will need to re-implement it from scratch. @klokan, thanks for the heads up.

Yes, that's what Mapbox has taken issue with with osm2vector tiles.

we have diverged since then

If either MB is okay with this or their claims have no merit then it's fine.

@nyurik the SQL of the OSM2VectorTiles project were written by @lukasmartinelli and @manuelroth, independent of Mapbox - equal situation to this project.

No data were copied from Mapbox servers in the OSM2VectorTiles project - not a single vector tile is 1:1 equal to Mapbox.

Mapbox seems to claim that any independent implementation of vector tiles, which are compatible with their vector tile schema and openly released styles is illegal - they claim that the selection of the data from OpenStreetMap database for the individual zoom levels, the choice of attributes and names of classes etc. cannot be reproduced by third parties and used outside of their hosting service.

Therefore WikiMedia may be affected as well...
