I don’t do it myself, of course, as I prefer to pay for what I obtain. But technically there’s nothing legally or morally wrong with file sharing. At least IMO.
“technically” and “opinion” are not on the same realm.
Technically there
is something ‘legally’ wrong with it
under certain conditions/circumstances (i.e., if the material is copyrighted, if the ‘friend’ uploads it to a site which is under investigation for pirating, if the ‘friend’ uploads material by producers/artists openly known to object to having their material distributed in this manner, etc.). Laws are rather technical in their wording, so one cannot brushstroke a broad opinion of all file sharing as being right or wrong.
Morally, that’s not a matter of opinion either, as it is based upon the moral ‘law’ God inscribed into our hearts and onto stone tablets. Thou shalt not steal. Thus, once your investigation into the civil ‘legalities’ of participating in filesharing sites hits the first barrier of going against even
one civil law, the decision you make to ignore or honor that law is on you. Moral law dictates you are to honor that law providing that law does not go against God’s law. To disregard the law - by your own intellectual reasoning - despite what you know about “Thou Shalt Not Steal” - puts you in the position of committing a mortal sin. Mortal because you know the civil law, you know God’s law, you know the consequences of choosing to disregard God’s law, and then you actually choose to follow through by disobeying that law.
God does not split hairs on matters such as these. Satan loves to rationalize every sin into being less of an offense than it really is. Do not succumb to his lies. Do your homework. Investigate the laws in your city, in your state, at your university (if you’re using university resources to access these file sharing sites) with regard to the particular site you or your friend are considering. IF everything you read confirms the files being uploaded can legally be downloaded, then your conscience is clear and you can participate. IF you find a single legal objection, I’d refrain until a civil ruling is made on the charge. Better safe than sorry.
If your friend wants the song that badly, let him pay $.99 for it, or better yet, do him a favor and buy it for him as incentive to stop risking his soul over a $ .99 song or a $1.99 movie (or whatever the going rate for paid movie downloading is).
