Some very simple comments on this.
1. Yes, artists need some way to get paid for their work.
2. Current copyright law is broken in far too many ways and was written before the Internet and computers.
One of the things I would like is the idea that I can buy a copy of something, a book, or film, or computer programme, or picture, or TV show or something, and I own a "copy" of it. I "own" a right to view/access it at any time in any way I like.
That, like owning a real book or VHS tape or DVD, means I can watch/view it, and the choice of device on which I do so should not be a problem.
Indeed, like a book, I can lend it to friends and family - maybe some "family sharing" system as iTunes has.
I am pleased to say that some systems are close to this, but within each system. I have paid for loads of movies and TV shows on iTunes, and some on Sky TV. I have paid for books on two types of e-reader things including Kindle.
But ideally I should only have to pay once, and I "own" a copy. The platform should not matter. I can understand if there is some nominal fee for spreading what I own to a new platform - cheaper if I do it in bulk for all I have. But ideally once I own a copy of NCIS Series 1 Episode 1 in HD, I should damn well *own* it!
We need copyright law that allows the various platform operators like Sky, and iTunes, and Amazon, and whatever (XBOX?) to be able to recognise that somehow I own a copy of something and therefore be legally allowed to stream it or download and play it to me on any device. These operators make money selling me new content and by ongoing subscription or such.
Basically, the underlying notion of "copying" being the right that is protected is bullshit and nonsense. It was created in a time when copying was a "hard" thing to do. Now we live in a world where copying is transient and costless in all practical terms. So we need the idea of a person owning a logical "copy" of a work and once they do so being able to access and view that as they wish with the underlying "copy" process being totally irrelevant.
