The question isn't if Canon can sell to China now. The question is when Canon decided to invest R&D into this machine, did they have any idea that China would be cut off from this product?

I assume that Canon definitely wanted to sell to China.

But now the market is severely limited. TSMC uses ASML. Intel uses ASML. Both aim to manufacture the most cutting edge chips. That's where the money is. In addition, both TSMC and Intel own a fairly decent amount of shares in ASML.
