Saying that, they themselves really need to look at Baidu, or Alibaba.
In the approach of "throwing money on the problem until it works" few can beat them. Alibaba's losses were surreal when they tried to get even to the tenth of AWS scale, but they went way further, and now they are profitable.
Alibaba and Baidu have a totally other market segment, which is domestic Chinese companies that want and need to be fully compatible with Chinese law for domestic data hosting, retention, government compliance. There is a venn diagram overlap between the markets addressed by the (AWS, Azure, DO, etc) and the Chinese virtual machine providers, but it's nowhere near 100%.
If not for China they wouldn't be where they are and wouldn't have succeeded. Having a large core market you are the most competitive in (due to government regulations) provides a massive upside that you can then leverage in other markets.
