And here is the problem, which I see in today's world. Publishers and governments do not see the customer in possession of what he paid for, but merely "leasing" it. Meaning, you buy the movie, but you don't own a copy of the movie but the license to view it. With this understanding comes the (in those institutions way of thought) that altering it, remixing, shortening or peeing on the booklet changes the product itself and is to be pursued by law. What really pisses me off is the fact that everybody on the planet is (thanks to ACTA and others) under general suspicion and state/police institutions are allowed to sniff my computer and everybody else's just to have a look whether you are doing bad things or not. I mean WTF? If I sneak into your bedroom and watch you 6ang your wife, just to make sure you are treating her according to the law, I clearly am a criminal. But THEY are allowed to? Sorry, this is a major break of privacy, and it happens now, and all we can do is sit there helplessly and wait what comes next.
In my experiences, I only know that when the guy giving something for free is taking money away from the owners, then they'll sue. So if I made a remix of a new Rihanna track, post it for free download, and suddenly DJs and Rihanna fans all over are downloading my remix over buying the original tracks, then the label will make trouble...even if my remix sounds very different from the original. This is why I never worry about all the mixes I have posted on my site. To this day I don't think I'm taking any money away from anyone...hence why I never got more than a "THANK YOU" from labels for using their tracks.
