I doubt it hurts very much. Are the names of these people even public? I don't think that many companies really do the kind of due diligence for IC positions that would discover someones involvement in a stunt like this, beyond maybe a couple of employee provided reference checks. Besides, there are plenty of ideologically sympathetic hiring managers in the industry.
