Imagine there's a website that sells "how to make money" products. Then in the salespage I tell people that they will get to download an exclusive video on making money once they've bought my product. So let's say they have paid and subscribed to it... in the "Thank You" page, it's a 4shared link or some mediafire link to download the competitor's video. Is it illegal or legal? P.S: No, I'm not doing it.. I'm curious about whether is there any copyright infringement in this.
