Let's assume you have been doing this for ten years.
In theory, if you would have bought all of it, it would cost you $20K. So the industry thinks they lost $20K.
But you also share that with others. Let's assume with 10 other people. That's $200K.
Those 10 other people also each share it with 10 other people. That's $2 Million!
Let's also assume there are 100,000 people in your city and also assume they all share their software with anybody and anything. That's $2 Billion!!!
Given the absolute correct assumptions and estimates, you DukeNukem, owe the industry $2 Billion!
Now the industry does not have to sue the other 99,999 people in your city.
But if they did, your city would owe the industry $200,000 Billion dollars!
I love math!
