Unionization takes public support, it's not something done in isolation (hence why there's all sorts of articles about Kickstarter's attempt and unionizing - they need support). Public support is a zero-sum game, therefore unionization is a zero-sum game.

If I give my limited attention to this unionization effort, then I may not give it to someone else. And maybe there is a workforce who doesn't have the eye of the internet who are trying to unionize, but now kickstarter has taken all the space for that news category.
