Might’ve gotten mixed up with CMOS dominance, or I’m ignorant.

I'm guessing is what they're really talking about. Which is not about NAND gates.

Just to add a bit, but modern digital circuits are almost exclusively MOS, but even the "complementary" bit isn't universal in a large IC.

I believe you're not ignorant. But many folks probably lack the process knowledge (CMOS) required to understand why :-)
