Not all evil looks that way to outside observers, unfortunately. I believe that the assumptions of FB that allowed it to get so big, "optimize engagement above all else", built a system that in many ways is at odds with the values of our society when everyone is a user.
Internally at FB, everything looks good, you hit all your OKRs and believe users are better off. Maybe you don't, but you're bonus is huge so you'll put your head down and keep on. Externally, it's an entirely different picture. Connecting people is a comically small issue society needs FB to solve, relative to our need for them not to harm children, or promote extremism, or hide research when testifying to congress.
