> If apple doesn't go to them, I think the only other option is Samsung?

Shorter-term that's true.

Apple is well known at times to think longer term on logistics, strategy. If push comes to shove, there are two additional options for Apple.

1) Political. Taiwan not being China depends on the support of the US. Apple is a economic security prize for the US, a strategic asset. Apple can get powerful politicians in the US to lean on Taiwan, which can dictate TSMC's behavior to an extent. This would prompt increased compromise from TSMC (3-4% hike, not 6%).

2) Apple starts investing into fabs and builds a TSMC competitor from the ground up, perhaps in alignment with ASML (Europe very much wants an improved semiconductor context) and a few US partners (build the fabs in the US and Europe for national security purposes). Apple is one of the few companies where you have to take this potential seriously, they can safely bankroll it entirely by themselves if necessary.
