Facebook can promise to put itself out of business, spending its cash reserves on development of an ecosystem of interoperable, open source, fully decentralized solutions to replace all of what it does with no central authority and no possibility of censorship or surveillance.
It can find ways for this new decentralized network to be accessible in China, unlike its current platform.
Instead of saying "we'll consult with safety experts, law enforcement and governments on the best ways to implement safety measures," it can expressly refrain from working in any capacity with governments who seek to inhibit speech or expression on the internet.
It can disclose all of the algorithms and decisions that produce the news feed and allow people to opt in or out of them, ensuring that their news feed is not a means of manipulation.
I mean, I can go on and on course. None of this takes any serious genius, just a decision to prioritize freedom and justice in society over money.
