Boneyback I dare say they aren't, but why would you expect any other professional who gets paid based on what is essentially commission to offer their product for free?
It is in the interest of every artist that another system is developed so that the public can access music easily, while the musicians still get paid for their work. Being a performer, especially musicians and actors, is generally thought of as 'not real work', probably because it is a very swan-like industry for want of a better way of explaining! Appears effortless and glamorous from the outside, but everyone is scrabbling and working on a knife edge inside. The area I work, the attitude 'you are only as good as your last performance/track/etc.' very much applies. A mistake can cost you your whole career. People a very quick to criticise, and yet don't know about the revenue streams within the business. And it is a business ! Careers on the line here, and in the last few years the business really has been strangled.
Can you honestly say if you were a leading figure in your field, and the vast majority of people were accessing your product for free, penalising both you and those less successful than you, you wouldn't stand up and say something? Why shouldn't they protect the careers of musicians, including themselves? Why is that wrong? Is it because they are wealthy and successful? Bearing in mind they are the extreme extreme minority, and many performers struggle to break even, especially now. Is it because you believe it is too easy or fun to be a real job? Yes, it is a hugely rewarding and exciting and all those things but it is also really, really difficult and it is never, ever easy.
I'd be interested to know why you feel that it is your right to consume these products without paying the people who created them?
