If it wasnt for the legality of the way torrents are used to infringe copyrights etc people really overlook how easy it is to transfer really large files like 10+ gb with torrents, you dont need google drive / skydrive / dropbox etc or anything of that sorts.
There are quite legit torrents around there and yes, it's quite a great way.
But only to distribute files (size independent) over lots of users.
And that's why there is also a load of copyright infringing content.
But is it the problem which content people download or is it the hole copyright idea wrong instead?
Putting aside those who download and resell the contents (which yes, it is wrong), isn't that the way some of that content really reaches the public?
Would some of the worst movies ever, be seen by anyone if it wasn't for the "illegal" download?
Would anyone ever listen to Taylor Swift if it wasn't the mp3?
This reminds me the eternal dilemmas raised by MP3 and yet, nowadays it is the standard!
Between only two users I prefer sftp.
