But isn't that just the problem? The fact that somehow institutions like the RIAA have been able to twist the long acceptable technical difference between hosting and tracking into being the same thing in the eyes of governments, the law and often even the media?
I remember years ago back in the mid to late 90s you'd get laughed off the internet if you said someone had broken the law for linking to copyrighted material hosted elsewhere. It was clear a link was merely a reference and not itself copyright infringement but somewhere between them and now the lines got blurred.
From what I remember (and this is hazy so apologies if I'm wrong on some of the facts) it started with the idea that if you linked to an image as part of your page but that was actually hosted elsewhere it was actually classed as infringement, whilst I don't agree that using other peoples images in this way without their permission is exactly moral, I also don't think it should be copyright infringement or whatever it is classified. At the end of the day if you put a picture on an open web server unrestricted then you're giving permission to people to access that, if others link to it there are technical countermeasures available to prevent specific or entire groups of sites accessing it without going through your site first. Of course when these kind of precedent got set however it wasn't much of a stretch for the likes of the music industry to start applying it to links from say a US site to say a Chinese site actually hosting pirated content where at the time pirated content wasn't illegal to be hosted in that manner via HTTP in that country.
Of course the age of peer to peer followed and then again it wasn't a far stretch for the same figures e.g. the music industry to apply this same line of thinking to peer to peer.
The reason Sweden still treats linking as legal is because it does have technically competent regulators being a very high tech. country that understand the issue on a technical level, however even Sweden looks to be at risk now to idiocy and corruption getting it's way over intelligence and common sense.
I think there's a lesson to be learnt here and that's when it comes to enforcing new laws on the internet the default should be to default to the option that offers most freedom to the general masses as if you give even a little leeway to those willing to control the internet it wont be long before they extend that and start applying it much more broadly. A similar example is in some countries where filtering of child porn sites is being abused to filter sites governments don't agree with, whilst it's nice to think that child porn should be filtered it's not as clear cut when that could lead to censorship abuses. This is particularly the case when you factor in the argument that filtering child porn doesn't actually magically make child molesters go away and point out that perhaps it'd be better if police actually went and found child molesters rather than simply masked the problem over with a filter.
