Just an update on this, DJI now complies with the license now. they added
the notice on the map https://www.dji.com/pt/mobile/flysafe/geo-map

this only proofs that companies do take seriously a letter from the
licensor and OSMF should take action after companies ignore the requests
from the contributors to comply.

One fixed, few others company still need to do the same.
