As much as I support the anti SOPA cause, is this more of a hunger strike than a consequential action? The startups presenting at demo day need those dollars a whole lot more than the corporate venture arms need the investments. Money is money, no matter how stupid it may be.
SOPA is going to hurt our industry so much. It's going to be destructive for Silicon Valley.
Taking a stand is necessary. YC startups are going to have much a harder time is SOPA passes. Even from just an economic point of view, it's better to take some loses now than taking higher loses in the future.
A sacrifice is worth it assuming it provides some benefit to the cause. I'm not sure if this action is going to have any effect (hopefully I'm wrong though).
