> How do you suppose more innovation would have happened if instead of China, blocking US tech, they let them have the whole market from the get go and instead of WeChat there would be Whatsapp and instead of Baidu, there would be Google?

1. Competition breeds innovation. Monopolies and the like encourage stagnation.

2. How do you know Google would win in China if China didn't block them? Unlike Europe, China is extremely nationalistic. Even if the home brand was slightly worse, it would still probably win the majority of the market. Of course, the only thing stronger than Chinese nationalism is Chinese pessimism so we'll never know.
