What makes you say that? The description seems pretty specific about the end result being open-source and distributed as a gem.
EDIT: indeed, the $50-backers description alerts of a rise to $100 after the kickstarter. That has to be a huge mistake on their part.
EDIT 2: I just received information from Tom Black that the software environment, along with the lessons, challenges, projects, will be free and open-source. What will be paid are subsequent, related screencasts and online classes.
There are actually two components that the author is promising. The interactive learning environment and website will be free and open source, but the author is also planning on selling a premium, paid month-long course with extra content. The premium course is what's promised in the $50 tier, and what will cost $100 after the Kickstarter ends.
Edit: As the responses indicate, the premium course is probably against Kickstarter's rules. I didn't mean to imply otherwise.
The point is that people are trying to use Kickstarter to eliminate risk in a business venture. If you're good enough o charge $100 for membership for one of your website, do it. Take a risk. Be entrepreneurial. Don't be that guy trying to get other people to provide you back-door seed funding so you can just bolt if it all falls apart with an extra $10k to boot.
From the KS: "Launching a Kickstarter campaign is the best way I can think of to get the word out and see if there's real interest in this. I always try to focus my time and energy on things people want (easier said than done), and this campaign will help me figure that out. So if you want this to exist, cast your vote by pledging!"
I try to be civil and calm here but that is complete and utter bullshit. Kickstarter does not exist so people like this guy can get a few months rent while trying out his latest business venture.
