Kickstarter is a business and has no obligation to uphold free speech. They need to curate their projects to protect their reputation. What if they allowed filmakers to Kickstart porn movies? You could call it free speech and make no judgments about the act itself, but at the end of the day people would start to see Kickstarter as a slimy business that's willing to host any project as long as they get a cut of it.

Somewhat related: There's another site called http://offbeatr.com/ which is like Kickstarter, except it is exclusively for porn, sex toys, erotic art/literature/games, and other such adult projects. I don't know if they are perceived as "slimy" or not, but there are a lot of interesting, innovative projects on offbeatr.
