A long time ago, in a galaxy far, far away, the regulators took on a might software giant and tried to break its stranglehold over the humble personal computer. 

The software company fought hard and long, arguing that to fragment its product would diminish the customer experience.

In the end the regulators 'won'. And low and behold, consumers can now choose which internet browser to run on their Windows laptops.

Just like Facebook today? Yes, but I think the mood is different. Bill Gates and Steve Bullmer were aggressively defiant. Zuckerberg is clearly contrite. Meanwhile Google just announced investment to protect its customers from fake news (Google News Initiative).

When an industry starts to self-regulate then you can tell regulation is coming. Zuckerberg knows this. It was always going to happen. As well as regret, I almost sense relief in that interview with CNN.
