I think I'm on the other side of this argument. The US operates a fairly laissez faire capitalist system. The US has decided that it wants to encourage chip production in the US. There are a number of ways to do this - you can put restrictions on imports, you can create tax cuts locally, or you can create federal initiatives to incentive companies to do more in the US. There are pros and cons to all of them, but it's important to understand the US isn't doing Intel a favour - there is something the US government wants - strategic capacity to produce high tech chips, and it's spending money in the open market to achieve that. It could have gone down the other routes, but there's good reason not to. You impose tariffs? Maybe Intel just decreases production, you create tax cuts? You get exactly the same accusations of state subsidy. But what's happening here isn't a subsidy, it's a transaction, Intel is delivering something the US government is willing to pay for.
