For real human of course you need a more detailed model than the simple linear threadshold one which was amenable to optimization by their algorithm. With a more detailed model they probably wouldn’t have been able to reach 100% but wouldn’t have tried to (e.g. if there is a non-adaption term I’d have strived for 100% divided by the non-adaption rate or something). But that doesn’t mean that you can tipp tippable populations.
