I made two assertions and I believe both are true. You seem to be stretching what I said to some form of "and ASML has done nothing else on top", which I didn't say. Maybe I should reduce "their core tech" to EUV, but that's clearly what I meant if you look up the history of the company.

No, I just didn't find any evidence that ASML licences "their core tech" from US. Let it be EUV but I still can't find any sources on it. Do you have some?

You can paste that comment exactly as you wrote it into any search engine or LLM and get your answer.

The burden of proof is on you my friend.

As if, working for someone with such entitled attitude. You find something you think is wrong say what you mean or move along.

As if asking someone to support their pretty substantial claims is all of the sudden called entitled attitude? No, that's just how people reason about different views. You should understand that when you say something you should be able to stand behind your words. C/p a link that supports your view would have taken you 2 seconds. Yet you chose the ad-hominem strategy. Pretty telling for anyone reading this conversation.
