I can’t speak to the organizational problems you saw, but when you consider the quality of software that Mapbox was producing before the failed union drive – Mapbox GL JS, Rasterio, Shapely – what you’re saying is nonsensical. The latter two libraries have of course left Mapbox, along with their creator, and continue to see high-quality new features, but Mapbox GL JS is still so much better than anything else that I…
Shapely was around long before Mapbox, and Rasterio too. Both are based on stalwarts of the open source geospatial world - GEOS and GDAL.

Hats off to everybody who made it happen.
