I think you are missing my point
If you think the Uri Tzdek is a Leshem Mamom enterprise, and worthless and that might very well be true You need to think that there are alot bigger fish who are enagaging in Mafia style tactics Leshem mamom as well and are not doing it Leshem Shamayim.
If the 2nd and 3rd hashscha’s were really concerened about Kashruth and not Mammom they could just let the 1st Hashgha or the owner of the company Gratis information instead of making them buy another Hashghcha (Their own of course)
