The EP is no less Ethnocentric to ancient Greece.
The canons explicitly do not give the right to the EP to interfere in local jurisdictions.
Frankly without Third Rome, the Second would be completly gone, long since offed by the Muslims.
You seem to conveiniently ignore how much the Third Rome did to protect Orthodoxy while Rome and the Muslims both were after it.
"The EP is no less Ethnocentric to ancient Greece."
Huh? The EP, and the rest of Orthodoxy for that matter and under the leadership of the EP, condemned ethno-phyletism at a Pan Orthodox council in the 1870s. This was in specific response to the rise of "national churches" on the Peter the Great Russian model in the 19th century. Ethnicity had little or nothing to do with The Church before the Great Schism or indeed after the Schism until the rise of the chauvinistic 3rd Rome idea. The Faith isn't defined by ethnicity or nationality, though nationality, until relatively recently, was clearly defined by Faith. To compare the Eastern Roman Empire with the Russian Empire is a mischaracterization of history. The ERE was a Greek speaking Empire with a Hellenistic culture, but it wasn't "Greek", certainly nothing like ancient Greece. The Russian Empire was thoroughly, chauvinistically Russian as is the Russian Church. It was less true of the Russian Church prior to Peter the Great but what Peter created was nothing like the Church which existed in the Ottoman Empire
"The canons explicitly do not give the right to the EP to interfere in local jurisdictions."
The canons do give jurisdiction to areas outside the boundaries of the ancient patriarchates. Moscow, of course, is not an ancient patriarchate and the Church in Russia was under Constantinople for centuries. At least canonically, Moscow has zero jurisdiction outside its original jurisdiction as granted by Constantinople.
"Frankly without Third Rome, the Second would be completly gone, long since offed by the Muslims."
And when, exactly, did Russia save the Patriarchate of Constantinople? Certainly not after WWI and during the 20th century when the Turks effectively did wipe out Orthodoxy in Turkey.
