That's about the child not being a mamzer, since there was no bi'ah
asurah. RMF invokes it in that context, but the Satmar Rav holds the
child would be as much a mamzer as if the union were bederekh bi'ah.

: Of course if the donor is not Jewish, would not the problem go away?

Which is why I phrased the Satmar Rav's position that way.

But here we're talking now about the child happening to meet another
child of that donor and marrying a genetic sibling. Would *their* child
(produced in the traditional way) be a mamzeir?

Mamzeirus, according to RMF and general consensus, requires a bi'ah
asurah as one of the preconditions. That doesn't mean paternity
requires bi'ah. Maybe it is determined by zera. That's the comparison
I was making to egg mother vs gestational mother in the case of
surrogacy.

If the donor isn't Jewish, then they aren't halachic siblings anyway.
But it's possible that if the donor is Jewish, even RMF would say the
grandchild is a mamzeir.

Tir'u baTov!
