The CEOs one job is to set the direction of the company. To create a vision of what a successful Yahoo looks like.
In this article, it talks about Mayer being responsive to email, turnstiles, food, etc. These are things a mid-level manager takes care of, not the CEO. And these things definitely are not a strategy.
All the way up until recently Yahoo wasn't even sure what type of company it is--media or tech. This is not possible if the CEO is clearly communicating what Yahoo is and should be.
If you want a company full of team players.. forget about this idea of dividing them into 1x vs 1000x. Make the vision of the company clear, so that people know what they're doing and what success looks like. When you get buy in of your strategy from the employees, it doesn't matter if they're 1x or 1000x developer. Everyone is working toward the same goal.
