I would also apply it on reverse, if you're a company or artist who created content and put it online, why would you not expect that somebody will download it without paying you? If they can, it should be totally fine.

Let's compare an apple to a car to a software...an apple is physical, if you take it without pay, the company has one less apple. Same with a car. With software that's not the case. You can't touch it and there is an infinite number of copies to be had.

The Internet is similar to a street except for the fact that thief's can walk on it without having anyone know or care about what they are doing. So if you leave a software or artware on the street, there's a good chance that it will get stolen. Same with the interwebs.
