If you really think about it, all of the social media platforms make money from all of the people who use their platforms. Users dive in thinking they're on the next greatest thing, all while being suckered there so the platforms can earn billions off of them. Mark Zuckerberg, for example, made $41 billion last year from advertising. How would you feel about sharing in that?
Facebook is business for Zuckerberg and not for charity. Why would we ask for share of revenue if we are only using their platform for free? Advertising is where Zuckerberg earn his money and we are only tools to make his plaform successful.
