The explanation is that the two types of optimization are related, because the successful and exploding startups both consume our time and (perhaps more importantly) attention. If we can make founder disputes at the unsuccessful startups take up less of our attention, we have more left to use helping the successful startups.

Plus we're human, and we don't want to spend all our time mediating disputes. It's very boring.

I don't think outsourcing dispute mediation would work. There's too much context, and founders seem to want to make their case to us personally.
