Just to add to this comment; It's one thing for software developers in the government or a large "essential" corporation like a bank or telecom company to unionize. Those places get toxic because the work has to be done and gets very political because of the sheer number of people's lives they affect. I understand the labour issues around working for those organizations.
But kickstarter? You mean the funding apparatus for indie games and gimmicky consumer products? That's where you want to unionize?
