Your right to control the distribution of your creative work and the opportunity to profit from it.
People will very seldom voluntarily pay anything for things they can get for free. Basic economics.
There are all the New Age theories that preach otherwise. Most were tried out and thoroughly vetted back in the 70s and 80s. And guess what? It doesn't work. Other than a very tiny number of good hearted souls who will voluntarily give financial support to their favorite bands, the vast majority of the listening public doesn't think - or act - like that. And despite all the talk about "new paradigms" and "the new online business model," when the dust finally settled on the smoking ruins following the dotcom collapse of the 90s, those businesses that still survived were conducting business the same way humans always have - by selling things for actual money.
Now there's a newer generation who, for the most part, doesn't believe in paying for anything they can't hold in their hands. And while they might have no problem dropping $600 on the latest smartphone, they see little reason why they should have to pay for any music they might want to play on it. They've grown up with the notion that anything that's accessible online, or is able to be copied off of it, is somehow mysteriously and magically "free." Or at least should be free for some equally magical reason.
Most musicians and bands are caught in an unsustainable situation right now. They no longer have a product (i.e. recordings/videos) they can sell reliably. The have become a service business, complete with the abuses, long hours, low wages, and poor working conditions that characterize so many service sector jobs.
Even the hoped for revenues from ticketed live webcasts have been minimal. Which provides further evidence there's a widespread belief that anything that is made available via the web "should be free." Were it otherwise, paywalls would not have met the resistance they have.
Welcome to the realities of performing music in the 21st century. For most bands, it's going to be a hobby at best.
