>This is not exactly right regarding Ukrainian. While it is the official language of Ukraine, in reality... let's say that not all Ukrainian people are actually speaking it.
your "adjustment" didn't propose what other Slavic language would outnumber Ukrainian to be 3rd behind Polish and Russian, so you didn't move the needle.
Problem is that language debate in Ukraine is extremely heated and thus self-censoring kicks in. Let's just say I personally believe that there are very few native Ukrainian speakers and let me say in advance that of course I am obviously very wrong here.
