Piracy is or good!

I always thought companies like Microsoft were fighting against piracy. But never for a moment realized that it could actually help the company as well. Quoting the text which says so:

For one thing, there's no reason to think that a given user of pirated software would have actually purchased a legitimate copy. Furthermore, the argument ignores the fact that companies actually benefit in some ways from piracy, because a user of pirated software is likely to purchase software from the same maker at some point down the road.
