The company that produces XYZ, a computer spreadsheet program, estimates that millions of illegally reproduced copies of XYZ are being used.
GIVEN THAT
There is a company wide effort to boost sales
AND THAT
Illegally pirated copies of XYZ software would have represented millions in sales, had they been legally bought
WHY IS IT THAT
The company isn't taking legal action against the people who have an illegally pirated copy of the software?
EVALUATE
We need to figure out why this company isn't going after people with pirated copies of the software. Seemingly, they could boost sales of XYZ by cracking down on people who illegally pirate the software.
Punishing those people wouldn't itself boost sales, but presumably it would be a deterrent to others, and so someone who was considering buying vs. pirating the software might think, .
Maybe the company doesn't trust that punishing the people with illegal copies would actually have a deterrent effect. Maybe they think future customers will think "pirated copy vs. nothing" rather than "pirated copy vs. purchase a copy". Maybe they think future customers would never hear of these prosecutions and so those prosecutions couldn't have a deterrent effect.
Maybe the cost of pursuing legal action would be more than the future sales brought in by more people buying legal copies (and so it would be a net loss of company money).
Goal
Let's find a story for why the company isn't trying to legally punish the people who have pirated copies.
