I thought Taiwan prohibited export of this kind of know-how? What did I miss?

Advanced lithography is like if a mystery cult were real: Secret knowledge only understood by the most learned initiates, tightly-guarded process, etching symbols that do things...
Sadly true.
Even more depressing: it's like a very complicated baking recipe arrived at by tweaking parameters over and over a again. There is no deep understanding... just a giant list of baking parameters that seem to work, sometimes.
(Yes, a bit like an AI. Hmm....)
Wow I did not know this and it is fantastic news, surprised Taiwan allowed this as they see chips as being the most important reason America would intervene if they were invaded.
In case of invasion, it's not that unlikely that the fabs in Taiwan get destroyed, or at least lose the ability to keep making and selling chips while the conflict is hot. In that case TSMC and Taiwan might prefer having a backup. As long as the US doesn't confiscate the Arizona fab, effectively siding with China, Taiwan would arguably have more leverage by still having something of immense strategic value to trade.
The US is not going to hold on to some working fab for some Taiwan-government-in-exile. As soon as you are out of power, even your allies generally take the time to plunder what they can.
In the case of invasion, the equipment within the TSMC factories will be affirmatively destroyed / sabotaged to the extent that it can't be used or studied.
I'm a China dove and I'd favor full-throated defense of Taiwan in any invasion (much more so than Ukraine) regardless of chips.
They have adopted a n-2 type of rule for advanaced tech...but as of yesterday they seem to have relaxed this rule and approved transfer of 2nm from Taiwan fabs to the AZ fab at some point in the near future.
