SCOBA was originally formed to help form a unified hierarchy in the USA. However, the EP was not happy with it as he wanted control of SCOBA so there was friction.
When the new Episcopal Committee was formed, it was largely through the efforts of the Orthodox Christian Laity (OCL), a group of very rich men who are largely of Greek descent and who support the EP. The OCL provided the venue and contributed large sums of money in this endeavor. The OCL are more cultural-political Greeks (Greeks in name only) than deeply spiritual men. Recently the OCL broadened its membership to include prominent Antiochians who are more devout World Orthodox.
When this new Episcopal Committee launched, not surprisingly, the Orthodox Church in America (OCA) was not recognized as it is not recognized by the EP, whereas OCA was recognized in SCOBA. So, yes, there has been a political shift, and not surprisingly, the True Orthodox monastery at Mt. Athos has been under more persecution and is receiving less support from Orthodox Christians in the USA.
It seems that the consensus of World Orthodox in the USA favors being under the EP. They forget their history whereby Alaska and SF had sitting bishops from the Russian Orthodox long before the Greeks. Sadly, the EP is acting more like a Vatican version of a Roman Pope.
