Is it possible that we read it so often because it's obvious and undeniable?
In fairness, I do agree with your assessment that the moralizing of figures like Musk and Zuckerberg has gotten old. But it's old because we've been criticizing them for years and nobody responds. Elon and Mark are net-negative fraudsters that manage to stay liquid by spiting humanity. They do not bristle at the thought of invading your privacy, surveilling you or deceiving you through complex marketing campaigns. We have seen the same behavior from Nadella, Pichai, Cook and just about every other executive capable of redirecting their respective business.
In the interest of discussion, I'd challenge you to defend this trend instead of downplaying it. Why shouldn't we prosecute anticompetitive and misanthropic market abuses? Help me understand the sympathetic angle.
