Good article about Jack leaving Twitter.

I’m not the only one that has argued that Facebook’s biggest problem isn’t divisive content, hate speech, or misinformation. Facebook’s biggest problem is Mark Zuckerberg. Not only does he exert total control over the direction of the company, but Zuckerberg is also unable to see the company for what it actually is—leading him to make decisions that have consequences in the real world.

Even in the case of Twitter, where Dorsey was known to have delegated most decisions to his deputies anyway, it’s important to have someone with the skills, character, experience, and desire to actually lead the company.

The point is that when a founder lacks whatever it takes to lead a company beyond where it is today, that founder becomes—as Dorsey put it—a single point of failure. That might sound harsh, but it’s true, and it’s an important lesson for every leader.
