I like to think of it this way –
What if a power had access to everything Google 'knew'? What would they have?
A: The Zeitgeist - what it is right now that people the world over are 'seeking', what they crave.
What if that same power had access to everything Facebook 'knew'?
A: What the world was 'feeling'
What if they had everything Twitter 'knew'?
A: What the world was 'saying'…
Now… imagine all 3, in a feedback loop, driven by AI and algorithms – providing this power access to, and cross-referencing ability of … it all… (((they))) could easily 'steer' what the world perceived by gentle shifts in presentation, framing, and yes, at times, not so gentle censorship. The ultimate control grid.
The best prison is the one then inmates are unaware of.
