How can YC be responsible for something their former executive does? And more importantly, doing one thing while advocating a policy prohibit the exact thing isn't necessarily wrong. If the tax rate is 20%, and I advocate a 25% tax while not paying the extra 5% until the law is passed, I would say there isn't any contradiction in my actions.
