I don't understand what you're disagreeing with exactly. I say "unpaid overtime" appears to be legal. I didn't say "unlimited unpaid overtime".
From everything you quoted, "unpaid overtime" is legal as long as it's clearly transparent from the contract and it's within other laws restricting the amount of hours total. Unpaid overtime is statistically common as per the other sources I linked to.
Obviously, if unpaid overtime clauses were clearly and entirely illegal, the lowest court would've immediately ruled in favor of the plaintiff, not against him.
