The majority of the content online is not created by startups, I would wager that the majority of the internet couldn't care less about your little startup circle jerk. To suggest that any single country "owns" or contributes most to the internet is laughable. I never use content created by china, that doesn't mean it's non-existant.
The majority of content on the internet is trash as far as I am concerned, but if you read carefully what I write you would see that I am talking about value. Chinese entrepreneurs create valuable resources, that allow Chinese users to use Internet for their benefit, which includes creating content that we might consider as trash. Without Chinese entrepreneurs there would be no Chinese internet, just a collection of Chinese government sites that nobody uses. Same goes for Russian, German, Israeli, British, etc. etc. and yes - AMERICAN entrepreneurs, who should be the first on this list, whether you like it or not.
Majority of the Internet IS what you called a startup circle, because that's who builds all the resources people like you use. And to claim that I claim that a "country" owns the Internet means you don't know how to read – I stress that Internet is essentially owned by those who create resources and supported by those who use those resources – not by the governments of countries who think they can make rules and do whatever they want. They can do it physically – and end up having no value left, because those who create value have departed.
