Facebook is just the final form of the monster that silicon valley continually creates. Every unicorn software startup has the same strategy: create a competitive app, get VC backing, blitzscale until you are dominant, then abuse your power to monetize the platform.
The only difference is how far along a market is in the cycle. Desktop operating systems went through this in the 1990s, eCommerce went through this in the 2000s, smartphone operating systems went through this in the late 2000s, social media went through this in the 2010s, ridesharing is going through it now, autonomous vehicles will go through it soon, and AI platforms will go through it when they arrive.
It's the same story everywhere you look and the process begins at the startup stage. Attacking companies that reach the end of the cycle won't stop the cycle from happening.
I would love to see Apple, Microsoft, Amazon, Facebook, and Google broken up. I would cheer it. But it won't save us. It will only change who owns the leash we're controlled by.
I don't know about anyone else, but I don't care whether I'm being controlled by a millionaire, a billionaire, or a trillionaire. I just care that I'm being controlled. The only way to escape is to own digital infrastructure that you rely on and that possibility only exists with free and open source software.
