I think the most important point you are making here is, who decides which question needs to be asked to the poskim?
The RC's are all established poskim, and have all written seforim in their expertise (is, or at least was, a requirement). Any shayla that has a psak there is an internal teshuvah written to explain. When there was a machlokes between RYB and RHS, which was not infrequent, I'd imagine the CEO was machria, with input from the RC.
As far as this stuff goes they are leagues better and more transparent than almost anyone else.
Keep in mind that 23% of American Jews keep kosher at home, at least on some level. The OU is the symbol of choice. Muslims rely on it for Halal. Chassidim never relied on it, and uber yeshivish also not. So the demographic we're discussing, the yeshivishe crowd, who may not rely on RHS (which is ill advised IMHO anyway, and I am a card carrying yeshivish crowd member who had the zchus to talk to RHS about many topics), is, even long term, a very small part of their clientele.
