I suggested also supporting the central map repository, though Wikipedia with its massive bandwidth requirements might just be more in need. I would also say that most map type apps now use OpenStreetMap, all for free.
Maybe they too should be supported 'mandatory'. That word, as you can tell, I found slightly puzzling.
I support Wikipedia and they tell me I am one of about 10% who do. Once again, if we use it we should support it - if we want it to be around in ten years.
