What he won't support is them raising prices mostly for Nvidia. TSMC has done this in the past as a clear move to cut nuisance production, and nvidia's books are full of nonsense orders that they can't possibly fill. Wei isn't an idiot, unless Nvidia fronts a lot of cash, it's unlikely to work out in Jensen's favor.
Then they’re going to have to compete with Apple on pricing, and nothing would make TSMC happier than Apple and NVIDIA in a bidding war for fab facilities.
