Can't say that I know anything about the money TSMC makes or how much of that Bitmain is responsible for; but I could see news like this affecting them more than Bitmain at the moment. So this statement may be nothing more than reassuring their business partners that they 1) Have no large amount of outstanding debt they may not be able to recover and 2) That they do not have any particular large customers that are ATM going out of business creating a potential sales void.
