The same way they strong-arm TSMC into giving them exclusive first dibs on new process nodes - by having more money than God and making an offer they can't refuse.

To strong-arm someone means to impel them by physical force, especially against resistance, not to give them so much money they'll be happy to cooperate. That's basically the exact opposite of strong-arming.
