He is walking a tightrope between the young activists and the more traditional members within the democracy movement. He knows he is walking a tightrope on just how big his company can grow before the public turns against it. Note: You can call someone's attempt to deal with this type of situation a tightrope walk. The strategy is something of a tightrope walk.
