Validation labs do not get or want money for backdoors.

So, either quit your conspiratorial nonsense or take it to Hollywood,

Of course they're subverted.  We have Ferguson et al show how they could be backdoored.  We have internal NSA documents reported as talking about the subversion.  We have confirmation of RSA (inadvertently or not) accepting money to put a EC_DRBG as a default.  You yourself just said the validation labs are demanding the backdoored P & Q be used (and rejecting the provably uncooked implemented chosen parameters presumably).  NIST put the standard forward (inadvertently or not) from NSA input.

I am non-plussed at what you could be trying to say with the above statement.
