Wrong borders on map - risk of legal claims
The map you are using is not consistent with international law. In particular, the Crimean peninsula is depicted as a part of the Russia. Which is wrong as russia recently occupied the peninsula. Occupation was not recognized by international community.
Showing Crimea as a part of russia may result in legal claims for propaganda of international wrongful act.
on your link to the Open Map, we see the Republic of Crimea as part of Ukraine,
and on the site of Windy com - Crimea, unclear on what grounds, is listed as part of Russia.
