This is a situation where their requirements don’t align, so they’ll never reach an agreement.
GrapheneOS, for example, is also strictly against making the Fairphone line of phones a little more secure because it doesn’t meet all of their security requirements
In this case GNU won’t certify GrapheneOS as fully open because it includes binaries that aren’t open
