The fact is even if every single last newzbin type site got shut down for providing easy access to downloading illegal materials, we just go back the old and slightly more inconvienient days of, painfully, downloading headers daily and searching for the files you want. Tedious and slow at times, but not hard, set some headers downloading, go away for ages, come back and search for what you want.
The only easier thing newzbin offers, is help finding things you don't know about, IE finding an episode of house the day after its on is easy. But grabbing a film you don't know was posted, well you have to scroll through an entire list of 10k's of headers to spot it.
This case isn't against usenet at all, and they really can't shut down usenet and its not worth their time trying. The very worst outcome is back to the long winded method of finding files, the most likely outcome, is them being laughed out of the courtroom.
I've said a 1000 times, and mean it, if I could buy a monthly subscription to download my favourite TV shows legally, I would, their profits would massively increase and everyones happy. We'd also be able to get rid of the irritating and almost completely ignored adverts and shows would get obvious viewing numbers, and people can vote with their subscriptions/ratings more easily so you'd hopefully get less great shows canceled, because ad revenue from being on at some stupid dead end slot would become a non issue. Great shows would get watched, whenever is convienient, and the exec's would see things like Firefly getting huge ratings and it wouldn't have been canceled.
The thing is, don't we all know thats exactly where the tv/film industry is going in the future anyway, so why wait?
