It’s actually not, his commitment to MWI is more rooted in his ignorance of QM, not due to any metaphysical commitments. Plenty of people with actual degrees in the field all disagree on what the right interpretation is, even today we still don’t. Metaphysics doesn’t play into it, MWI is just one way to explain the math but it has it’s short comings.
Aumann’s agreement theorem doesn’t factor in here. The simpler explanation is that EY doesn’t understand QM, which is why he assumes Many Worlds it the only one. In fact he’s often extremely confident (and stubborn) about things he not only doesn’t understand but is provably wrong in.
The truth about QM is that no one really understands what’s going on there.

Presumably you wouldn’t say this of actual physicists who believe in MWI?
MWI is just one of many interpretations, I might not say it of actual physicists who believe it but if EY says it then one can ignore it.
The same way one can ignore him on AI and most things.
But in regards to what is correct on interpretation, no one knows for sure and we may never know.
