Maybe I wasn’t being clear enough. I know that all those terms have definitions. But in my opinion superdeterminism is not really falsifiable, and in fact very much more problematic than nonlocality as it actually appears in QM contexts.

In the most plain terms, the author is claiming that the collapse of the wave function can be explained deterministically if you just accept that it was preordained.

Superdeterminism is an interpretation, not a theory. It's only falsifiable by falsifying the theory -- which would also falsify any other interpretation.

Which means that "we must use a superdeterministic approach" is incorrect. It means that you may use a superdeterministic approach. If that approach is productive, that may cause people to favor your interpretation. But it does not rule out other interpretations. At most, it can make them sufficiently inconvenient as to dismiss them.
