To be honest I don't trust this guy. Facebook have extremely strong censorship and they are banning everyone for "hate speech" and monitoring user's behaviour (and ofc leaking everything afterwards). Facebook right now is extremely far from giving "the power to the people" and if they make their coin it will definetely be a garbage. I would rather expect something good from Telegram devs.
I'd invite you to check out our new project called Narrative. Our goal is to fundamentally reverse the way social media networks work by giving users complete autonomy and returning 85% of revenue to the users who contribute and participate.
We will also be using User Reputation to influence each user's impact on the network and the rewards they receive.
You can learn more about the project here:
