This whole issue is deeply rooted in historical events during Soviet rule in the 20th century and recent developments in Ukraine. It's also related to the fall of Constantinople, if you can believe it.
When the Soviets took over Russia and killed the royal family (God rest their souls), they also cracked down hard on the Moscow Patriarchate and all the national Churches in the USSR at large. Formally, it was because of the state atheism policy, but the Church also represented a threat to the ultimate power they wanted over the mind of the people. There were imprisonments in gulags, countless disappearances, mass executions, burnings of parishes, the works. There's a reason that the Church condemns Communism, we'll leave it at that. Still, many people were deeply angry with the Soviet government for doing this and continued to worship in secret. After plenty of crackdowns, the USSR eventually gave up and put up a dummy church that supported the state. This controlled branch caused huge problems with the rest of the Orthodox Church, since recognizing it or not recognizing it essentially amounted to a political statement on what the the Soviets were doing. In America, for instance, the Russian branch parishes broke in two – some loyal to the national Soviet church and others (correctly) calling the new Russian church illegitimate. The international divisions were long-lasting and deeply ingrained in the minds of those who lived through it. People considered those helping the Soviet traitors who betrayed their brothers in Christ; some Soviet loyalists bought the propaganda but others genuinely tried to save souls through the system. It was and continues to be a huge mess that we're still mopping up nearly half a century after the USSR collapsed.
Now, about Constantinople. When the city of Constantinople was conquered by the Turks, the Church was allowed to continue existing but only under strict control. It's a complicated situation and I won't harp on it too much – what you need to know is that the Church there was strictly forbidden from winning converts, building new churches, and even repairing existing ones. Aside from encouraging corrupt bishops from working with Turkish officials, the church was forced to become small and stick together fiercely. Over time, the Constantinople Patriarchate became synonymous with Greek identity in a time of occupation. This idea spread around the whole Orthodox Church in general and stuck particularly fiercely during the birth of nation-states in the modern age. Many Orthodox Churches are considered part of national identity. As you can imagine, this has led to a number of issues with outreach in new territories, the popular image of national Orthodox churches being only for a specific nationality of people, lax parishioners that only think of their faith as part of their image, and so on.
Like I said, this is a very nuanced issue and I brushed over a lot of detail – if you're interested, I'd suggest reading some more about how the Church in Constantinople survived in Turkey.
