Handing out sanctions without at least a plausible legal cover, sounds like a recipe for disaster that would come back to bite.

I wonder what could be used here, non-compete? IP infringement? Or doing it "for all mankind"?

As for knowledge, the YouTube channel Branch Education explained EUV lithography in great detail, sponsored by ASML itself.

My impression is that the knowledge is not that secretive, the precision required at every step is the key.

Yeah it reminds me of the Smyth report, published in August 1945 about atomic bombs, commissioned by the director of the real Manhattan Project. It’s fine to reveal knowledge in detail, if it doesn’t reveal anything related to constructing the apparatuses (the chemistry and the metallurgy) needed.

The press release following the bombing of Hiroshima specifically stated which method of refining Uranium was used. The U.S. spent a great deal of time, effort, and money on researching and testing four different enrichment systems. Just that one detail saved the Soviets 3/4s of a sizeable chunk of the A-bomb effort. Sometimes you don't need to leak much detail to give away a great deal.
