In all the time i looked online Ive never found a legitimate basis for these vague claims of drama around Graphene. See a lot of it in Louis Rossman circles (nothing against him, but he made a dramatic video on YT about leaving GrapheneOS) it's reactionary at best. Someone got blocked people got mad, full story only the ones directly involved know.
My point stands, a lot of petty personal stuff that seems unrelated to GrapheneOS. But there is never anything fruitful from engaging you types.
