Could you give an example for the 'eliminating weaknesses is more important than growing strengths' part? I think I've encountered this before - where letting an incompetent developer go would have accelerated a project much more than hiring a very competent one.

It's true, but real leader is responsible for his people and the team as much as for success. Team has to see that leader puts significant effort into making weaker people become stronger before actually letting them go. This way, healthy mutual respect arises instead of hostility and fear, because letting underperformers go always leads to fear, unhealthy competition, intra-team political games which are just a waste of human time and nerves.
