Even if, for the sake of argument, we accept that "send SIGINT to stop this program" satisfies "read[ing] commands interactively when run", notice the first part of the the text: "If the *modified* program normally..."

(Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) ---END QUOTE--- Take note that cdrecord is never interactive, so GPL 2c doesn't apply.Wrong. It displays messages by default and tells you how to stop the command etc. IMO this can clearly be interpreted as interaction.
What that clause is really covering is stuff like this: anthony@feynman:~$ bc bc 1.06 Copyright 1991-1994, 1997, 1998, 2000 Free Software Foundation, Inc. This is free software with ABSOLUTELY NO WARRANTY.For details type `warranty'. bc, unlike cdrecord, does actually read commands from standard input (its a calculator, if you're not familiar with it)
