Every time you think that these huge centralized platforms have too much power, remember that almost none of them provie direct services anymore. 
Facebook doesn't create its posts
Uber doesn't drive its customers around
Airbnb doesn't wash the linens in your rental
Youtube doesn't film their video library

All of these platforms only have the power of the content and engagement that WE give them. Without us, they are worthless.

Never forget that the simple act of leaving and taking our creations, media, engagement, and our value somewhere else, will turn them into nothing overnight.

This is why decentralization is the only path forward. There is no alternative.
