Because the fact is that BitTorrent is only gaining momentum. A huge number of people now get their music this way (and see nothing wrong with it, as noted by Tim Danton in another recent blog post). As I write this, one popular BitTorrent tracker is reporting over 21 million users currently uploading or downloading data. A recent study by Jupiter Research estimates that a fifth of Europeans actively use file sharing sites – twice as many as use the iTunes store.

Clearly this is a problem. When such a large segment of society is at odds with the law, something needs to change. But what? Do we need to rethink the law, or do we just need to work harder to stop people sharing music and video files?

Before we can answer that, I think we need to understand what we’re actually trying to achieve. I believe the presumption should be that people are free to do what they want on the internet (and elsewhere) so long as it doesn’t harm anyone else. So the first question is: what precisely is the harm that’s done by file sharing? Why, in a nutshell, do we care about all these people sending music files back and forth between their computers?

I’ll return to this subject in my next blog post; but before I do I’d be interested to hear your views on the above questions. So please, comment below and let me know what you see as the problem with file sharing.
