I would really appreciate if HiSilicon once again was allowed to fab via TSMC.

Fine if the US doesn't want to buy any of Huawei's products, but for us in the rest of the world. Please allow us.

That's TSMC's decision to stop activity with a sanctioned entity. Since they aren't under US jurisdiction they are free to resume it at any time.

No, current US sanctions against huawei says, any entity using US origin technology cannot fabricate Hisilicon chips. While TSMC is not headquartered in the US, they use US origin technology. For example, ASML EUV machines contain US origin tech, or they use Applied Materials, LAM research machines heavily on their production line. I am not sure how deep it goes, maybe even if the manufacturing line uses Intel CPUs also counts. That is for the legal experts to explain. As result, TSMC is under US jurisdiction with respect to this particular ruling. Maybe TSMC can risk it and supply Huawei, but US could retaliate by sanctioning them. At the end of the day, TSMC can't operate without US origin tech; if they can't get EUV machines or LAM machines, they are dead as well. So the choice is clear. And I am sure TSMC wants to be on good record with the US anyway.

You're mistaken. TSMC has no choice but to stop manufacturing for Huawei as TSMC's EUV tech is using US R&D that they and ASML have licenses from US research labs many years ago.
