I think that's only part of the argument. The other part is that, regardless of what's right or wrong, the OP thinks that using the software/service perpetuates it, and choosing not to pay for it isn't enough.
That's an excellent point, and in fact that's why I think people should cease consuming this content altogether rather than pirating it. If that was the focus of the argument, it would be great. But sadly, everyone who might listen will be turned off by the bit that goes, "you can't just choose to pirate stuff, because you just can't."
