In many cases, you are able to send a control-c, but the process that is generating the output receives it, not the process, the terminal program, that is rendering the text. You'd have to send a signal to the terminal program, which may cause it to exit and not be what you want. And doing is often done with UI controls, like a close button/action on the window. So it's not just priority inversion that is a potential problem, but also non-obvious layers of abstraction.
