This.
The strategic ambiguity is a message from the US to both sides of the Taiwan strait:
1. It deters CCP from taking over Taiwan,
2. It also deters Taiwan from changing the status quo.
But given the recent trajectory of CCP under Xi's dictatorship to be more aggressive, US has been more assertive of the defense of Taiwan [1] (though it is still technically a strategic ambiguity, unlike its Security Treaty with Japan).
