Russian Orthodoxy was a fake church created specifically to prevent Orthodox bishops from rejoining union with Rome after the Council of Florence. They arrested the bishops and elected their own, creating their own “church.” Although it was eventually recognized by Orthodox Churches, it took a lot longer than you’d expect. Now they are in schism against the rest of Orthodoxy, so perhaps the Council of Florence can finally find resolution. Never trust Russian Orthodoxy.
I think they believe that images of living things become idols. If I recall, Amish have similar concerns, but they don’t try to enforce it outside of their community. Fortunately, there was no such thing as audio recording when their religion was invented, so hopefully at least that’ll be tolerated. Radio broadcasts are better than no broadcasts.
