I haven't time to run through an entire case here, but I would like to air a view which I haven't seen in the papers:
I agree that forcing a business to take charge of copyright infringement will mean the effective end of free user-generated content. But is that really so earth shattering? I mean it is for some of the biggest websites online currently, like wikipedia. But honestly how bad is it if they fail? It's not as if this is awfully unjust. As Guard Dog will be happy to illustrate to you, govt regulation frequently strangles businesses on the vine.
These companies who stand to lose out the most are the biggest winners of the last few years. Youtube, wikipedia, facebook. I just can't get worked up on their behalf.
