In my opinion, it's best to leave what Facebook does out of the picture and focus more on how something like Youtube operates.
YouTube (Google) has been empowering creators on the platform through monetary incentives, production guidance and even a bloody studio. But YouTube doesn't have a problem with user acquisition or retention. Facebook is discovering it has a retention problem. Not as major as steemit, but at least they're DOING something about it.
Paying managers doesn't solve problems. Good managers solve problems. Paid managers can cause more problems. Paid managers can still get fired. Just compare it to any real world example that has paid management. If Walmart screws up, the managers get fired, Walmart keeps going because they hire people to take the fall.
Anyway, I'm not trying to be a jackass here.
Paying good managers solves problems much faster than hoping they'll do it for free. :)
And I know you're not trying to be a jackass. If I thought you were, we would not be having a dialog that's about to vanish into the unreadable thread zone. :)
