Well, you're advocating that unless something you put online is 100% your content (i.e. I couldn't post this because I'm quoting you if I was making any kind of profit off this post) it should be illegal. Have you ever heard of fair use? Perhaps you should read up on it. Our societies views on copy right law for years has been that you could not do a carbon copy of others work and call it your own, however you could take somebody elses work and modify it to be able to call it your own. Can you please tell me what violates IP law about the description you explained with the kid rocking out to Ghostbusters on Youtube? It does not upload the work in it's entirety, it is not willful infringement attempting to steal the content, and it's intent and purpose is for the kid to be shared with the world not the content. Also it allows for me to create backups of content I legally purchased for my own archival use. Yet DRM prevents that.
Let me ask you this, do you believe that Apocalyptica covers of Metalica (
