You forgot the juiciest parts:
- private company plays on legal gray areas on purpose
- private company invest aggressively to expand faster than law can react in order to grab said monopoly
This is basically capital cancer, they had a real value but dismissed everything a company is to a society:
- stable for employees
- stable for users
- stable for society
Any company can play rough when let loose with massive funds, but when reality occurs, just like anybody else, they'll have to round their corners and .. surprise.. they stop being interested and competitive.
