"Although many ranked voting methods exist, the Arrow Impossibility Theorem proves no single one can be ideal (Arrow 1963)."
That's not actually what Arrow's theorem proves. It just proves that a voting system cannot simultaneously meet four criteria. It doesn't prove that those four criteria should be required though. Independence of Irrelevant Alternatives is particularly problematic.
Kudos to them for respecting the Condorcet Criterion though.
