If I ignore reality and make up non-existent fabs, the extremely monopolistic, anti-competitive behaviour is not a problem!
>they are paying what they can afford.
The problem is not paying what they can afford, it's paying that in addition to forbidding TSMC from increasing their capacity on that node while the contract is ongoing. It's both paying what they can afford, and paying so that others can't afford it.
If some other company is willing (or really: able) to make a competing offer, I’m not aware of TSMC not being interested in that. It just happens that the number of companies with the margins to spend what probably amounts to the GDP of a small nation is approximately zero (or one if you count Apple)
Except they didn't have exclusive access? Huawei also bought 5nm. Intel contracted 3nm along with apple before backing out.
Is there any proof that this is actually true? TSMC is currently building few new factories, I suppose they will produce 3nm chip in them.
I am sorry but that is simply not true. Sigh.
If other fabs were available, apple's ability to pay up would not be leading to accusations of anti-competitive behaviour.
