Of course there are, you listed some of them yourself.
AMD and Apple becoming supply constrained means potentially less future business from them for TSMC. Intel has stated unequivocally that they want to their own fabs to reach parity with TSMC and take their customers … including whatever business Intel has sent to TSMC. If I were TSMC I’d want a prince’s ransom from Intel to make sure that no matter what I end up ahead. In fact, people thought it was in light of the shortages, but TSMC has instituted new rules about its fab capacity and its customers. Again TSMC is not Samsung or Intel when it comes to the foundry business. It isn’t just a division for them. It’s a different business model.
It’s the lack of transition to GAA that I’m referring to here. Right now they have node advantage. Depending on the quality of 3nm that could be important (think planar 20nm). However maybe there’s no problem beyond the delay. In which case return to point 1). Also AMD is not that small anymore (thanks to Intel’s missteps) and is reported to be on the same or similar node as Apple next year - some unspecified 5nm+ node, either 4nm or something else. It was you who brought up Intel constraining both AMD and Apple fabrication as a bonus to Intel getting TSMC 3nm.
