I disagree. Morality does not always equal self-interest, because people can react against their self-interest to uphold their morals. I would however agree with you that morality is a misleading word as it means different things to different people. I prefer the word Motivations.
It's clear to me that Tyberion ethics is centred on one single motivation. Protection of it's members. However they are far more motivations in the Cyberverse that are equally relevent and can often conflict. Loyalty to friends, loyality to a colour sphere, alliance well-being, alliance growth, providing entertainment, the wish to promote a political ideal, justice, revenge, nation-building, providing a community etc. etc.
Thank goodness there is such a mixture of motivations, as if there wasn't things would be pretty boring. It's the interactions and conflicts of these motivations that make Planet Bob what it is.
