Personally, if I see a company with "unhealthy focus on short-term profits at the expense of long-term strategy, growth and sustainability", I'm more inclined to get rid of the CEO. Treat the cause, not the symptom. Let the next CEO remove quarterly guidance.
Agree, but the CEO can also be the cause. We know that quarterly guidance does not compel every CEO to do this, Bezos for example. We also know that if the CEO is an idiot, irrespective of their incentive structure, they won't deliver a coherent long-term strategy.
