Lyons II was not a true ecumenical council. What the Greek party did there (the Greek heirarchs have tried and succeceeded at all sorts of stupid things in Orthodox history, such as monthelism, iconcolastic heresy, caving in at Lyons II and at Florence, embracing Calvin, "New Calendar" and proclaiming re-union with the Anglicans; thank God the Greek yayiyas and lower clergy never lost their Orthodox heart and saved the Faith from insane EPs).
We Orthodox recognzie the first seven Ecumenical Councils. Thise after the official split of the Church can not possibly be ecumenical. Read the 6th and 7th Council proceedings and read the Latin statement of their faith
We believe in God the Father Almighty, maker of heaven and earth, and of all things visible and invisible; and in his only-begotten Son, who was begotten of him before all worlds; very God of Very God, Light of Light, begotten not made, being of one substance with the Father, that is of the same substance as the Father; by him were all things made which are in heaven and which are in earth; and in the Holy Ghost, the Lord and giver of life, who proceedeth from the Father, and with the Father and the Son together is worshipped and glorified; the Trinity in unity and Unity in trinity; a unity so far as essence is concerned, but a trinity of persons or subsistences; and so we confess God the Father, God the Son, and God the Holy Ghost; not three gods, but one God, the Father, the Son, and the Holy Ghost: not a subsistency of three names, but one substance of three subsistences; and of these persons one is the essence, or substance or nature, that is to say one is the godhead, one the eternity, one the power, one the kingdom, one the glory, one the adoration, one the essential will and operation of the same Holy and inseparable Trinity, which hath created all things, hath made disposition of them, and still contains them.
At no time did the Latin Church use filioque at any of the Ecumenical Councils of the first millennium. Pope Leo III resisted Frankish demands that he add filioque into the Creed, even though he personally did not find filioque theolgoically objectionable.

Big SMILE!!!!!!!!!! ('course, my yiayia always maintained that Christ was a Greek boy and no Jew at all; you could tell by his name "Christos" so sometimes we have to be careful of yiayias, especially if they have wooden spoons in their hands!)
We outnumber you and it is an axiom of right reason and orthodox philosophy that more is better.
The greeks didn't exactly cave at florence, they noted that a Synod would have to review any potential conclusions and the Latins jumped the gun announcing union.
