This, rather incorrectly, presumes that the default mode of Facebook is "non-censorship," i.e. something resembling fairness in terms of what gets popular and what doesn't.
This is a huge farce, of course, it's all completely unfair pay to play and black-box algorithms.
Now, I could be wrong about this -- but it would be incumbent UPON THEM to prove that, by opening up and showing us how they do things. Barring that, I very much welcome insiders in Facebook applying pressure.
