Consider the following cases:
1. a company violates a FOSS license by incorporating GPL code and not releasing source code.
2. a company takes an image produced by an artist and sells T-shirts of it without the artist getting compensated.
3. a website/mobile app/elements of branding get replicated (or very closely reproduced) in a new website/app (think Zynga, Chinese/Russian clones of Facebook/Groupon and whatnot).
4. site content gets scraped wholesale, and fed into another AdSense-infested site.
In all these cases, noone lost any money when bits got copied (in fact, sometimes the offending party would produce original work to mimic the product in question), yet doing above things is a no-no, but downloading movies is OK. I don't mean to take a high moral ground here, but it's baffling for me to see the cognitive dissonance.
