Dear @TeamYouTube - Facebook stock is plummeting in large part due to slow user growth. I suspect constantly 'customizing' people's feeds away from being chronological, and preventing pages from reaching their followers organically played a large role. Don't follow suit.
Sadly, what social network usually do is exactly what people complain about other social networks. They don't learn from mistakes. But, what we think are mistakes are, actually, strategy which improve their income. So, who cares about people? Wallets are what they care about...
