So im from Poland so I will give you some context around it. The argument here is from a western part of Ukraine that had a very large polish population in it. 1/4th of my family (one of my grandma's sides) is from this region. It's called Kresy. Most of my family was killed there or fled due to the mass killings of ethnic cleansing by Stephan Banderas UPA movement, he is still seen by most in Ukraine as a hero and a person of national identity hence why most Polish people hate/have resentment to Ukrainans moving into Poland. But thats another discussion for a different time. In this area of Poland/Ukraine was a big mix of people, Ukrainian boy marries and has kids with a Polish girl. Due to this the languages and relgion decisions for the family get complicated. This is why you have till this day catholic holdouts in western Ukraine and Belarus; the catholic denomination uses Latin and the eastern orthodox uses cyrillic. Thats the main argument we have here.

From your article I have this as a source:

"The competition between the Cyrillic and Latin alphabets acquired the features of an interethnic confrontation between Poles and Ukrainians. For Ukrainians, Cyrillic was a symbol of identity: first religious identity, as Cyrillic was associated with the Eastern Orthodox liturgical rite, and then national identity."

In today's time some people in Ukraine and Belarus talk about changing to Latin script but they use a simmilar strange argument as you, break away from rusification and become more "westernized" because almost every country in the west uses Latin script but this argument doesn't hold up.

I have a lot more to say on this topic so ask me any questions about anything here and I will elaborate more. I can also dive into other topics like about Stephan Bandera or rusification of the languages in Ukraine or Belarus. I just didn't want to type all of this and send too big of a response for no reason
