I.e. is it that Organic Maps just have different priorities than you do? Or is it that Organic Maps have been holding back these good features for no good reason?
And yes, amount of work done on OM has reduced significantly, as many contribturos have moved to CoMaps.
Still, features-wise priorities of both projects are quite similar. E.g. being easy to use and simple , offline-focused, etc.
I would say CoMaps is a bit more serious about privacy and is also more open to customization by users (to a reasonable extent).
As CoMaps is a community-driven project then it's possible that with time the growing community would change the direction of the project somewhat.
But the biggest differences that actually were the reason for forking - are in the way the project is run - CoMaps is truly community-driven, open and transparent, which includes project's finances and decision-making.
