No, OSM is free for everyone, doesn't matter if you make profit off of it or not, so they don't have to pay for anything. They're choosing to support OSM to help it improve (which is also in their own benefit).
Sorry but this is just bs. The only important feature that's behind a paywall is downloading offline maps for more than one country at the same time.
And services like this have to pay for the development and upkeep costs in some way, since they're not selling your data like Google does. There's nothing wrong with having a paid tier.
Regular OSM doesn't have elevation data as well as many other info that mapy does provide. And the map visualisation is much better than any competitor IMO, especially for hiking maps.
The verdict will stay in place even if she goes for an appeal. It can only be lifted if she actually wins the appeal but the chances of that are practically zero given the evidence.
Some quick info: The kingdom of Nri was an Igbo kindom which existed from the 9th century untill 1912, when it was colonized by the British. Here are some more pictures of what it used to look like and the art they made.
I don't really use Organic Maps, but mapy works perfect on mobile in my experience. One big difference is that Mapy mimics the look of traditional paper hiking maps, which makes it much more convenient to read. Organic Maps has more of a standard OSM look, making it less convenient when you're using it as a hiking map.
