Those are still a cause for chip shortages as crypto customers bid themselves to the front of the line at TSMC:
"Chip manufacturing is already under huge pressure to meet demand, and TSMC is facing a serious water shortage in Taiwan on top of that.

Anyone attempting to place new chip orders in the future may end up with a different outcome, though."
