I fully agree that asking shadchanim whether the nasi project is a good idea is the like asking someone if they mind getting an extra several (tens of) thousand(s of) dollars. Clearly these are the wrong people to ask. Even if they oppose it in principle, they would be foolish to publicly say so.
The nasi project changes the playing field and discourages shadchanim from redding girls who aren’t part of this program.
Simple question: Is nasi helping or hurting those who don’t join their program to give outrages deposits (in advance) of money for shadchanus.
Before you hurt anyone atleast give one name of a leading Rav who endorses this program.
