The comment at the bottom of the page is pretty hilarious:
<b>Why is Storyboarder free?</b>
Storyboarder is niche software. The market is tiny. There's an inverse relationship between the market size and price we have to charge to make money. We are building this tool for ourselves to make better movies. We make money making movies, not software. We believe creative software should be free. Let's be completely real – I've never known anyone working on dope ass shit to be paying for the software they use anyways. Storyboard Pro - Shitty software that costs $1000? Boords and other online software that just allows you to order images and costs a monthly fee? Fuck those guys. And fuck Sony Pictures. They make the worst fucking movies. What does that have to do with free software? Not much. Maybe use free software to make great movies and don't waste money going to a Sony movie? Fuck. And fuck Dave Morin. And Gary Vaynerchuk. Ugh.
