As a contributor to OSM, I didn’t know about what was going on with Organic Maps. I might check out CoMaps on F-Droid to see how it compares with OsmAnd~. Thanks, OP!
Admittedly I only read this open letter and so am still too out-of-the-loop to say if Organic Maps is in the wrong here. Still, it seems like a sizable and competent enough fork that my initial bias is against Organic Maps.
