This revert contains multiple issues.

Firstly, you have no respect for the common English names for Chernobyl and Pripyat (yes, that's how they are spelled). It's not for Ukrainian nationalists to decide how English is spoken in a country that is quite literally erasing any other language than Ukrainian via their legal system. I find it quite odd that OSM can't use the common name because one mapper, who commonly used slurs and supports the death of children, has an issue with "Pripyat" and "Chernobyl" (again, the correct spelling). My edits were there for months until he noticed them on his crusade against anything that sounds Russian. It's also worth noting that unlike places like Kyiv, Chernobyl and Pripyat have not had their common spelling changed in English. Even Wikipedia, where the common spelling is used for the title and article, uses "Chernobyl" and "Pripyat".

Secondly, you reverted some completely uncontroversial edits. I'm not allowed to capitalize letters now? Perhaps capitalizing letters draws the ire of Ukrainian nationalists? Please do explain, because I'm not seeing any good reason for that revert.
