Here's the problem:

In attempting to fulfill Facebook’s current mission — to “give people the power to build community and bring the world closer together” — Zuckerberg and his team of Silicon Valley–based executives failed to foresee its malignant applications: misinformation, propaganda, rumor, hate.

They didn't fail to foresee. They failed to be responsible. There's a world of difference between "to give people the power to build community and bring the world closer together" and "to build community and bring the world closer together."

Facebook was created so that Harvard boys could rate Harvard girls without the girls knowing. This whole "empower community" thing is a speculative side-benefit of the core mission of social media apps, which is monetizing jealousy. By saying, "well, people could use it for good if they wanted" those collecting the checks absolve themselves of all responsibility for any actions or behavior other than "good" (for which they can claim credit).

Meanwhile, the organizations tasked with enforcing "good" have no more handle on the platform than anybody else. Generally they have a lot less.

And here we are.
