What regulations block Japan, Korea, Canada and other non-european countries from having this big ecosystem of internet companies?

Canada, albeit almost 20 times smaller than Europe has created a web company more than twice as big as the biggest European web company. Shopify. It has a market cap of over $50B.

Korea has Samsung. A $300B giant. Albeit not a web company, I would consider their smartphones part of the internet ecosystem.
