Do you know UAE or OMAN? Do you live here?
I do, and I personally know most of the places that I have indicated on the maps.
Please revert the modifications you have introduced, and do not correct my work, or I will have to report it.
In both Oman and the United Arab Emirates, although Arabic is the official language, English is the language used for both business and tourism, and all road signs and maps are also in English, since otherwise Otherwise, the majority of the population and visitors would not know how to identify them.
The National Atlas of the United Arab Emirates itself is written in English (romanized, but in English).
I have the impression that you have come to do language policy at openstreetmap, and I think that's not what it's about, don't you think?
The only way for OpenStreetMap maps to be useful in the UAE and Oman is if they contain the names in English and Arabic. Replacing them with only Arabic would make them useless.
On the other hand, it should not be forgotten that most of the place names of the villages and towns, especially in the mountains, do not even correspond to the Arabic language, since their inhabitants (semi-nomadic tribes) did not speak Arabic, but their own language (Kumzari and others).
