Because Netflix is razor-sharp focused on their core business? Speaking of their infra, Netflix focuses on productivity, based on a fundamental value that everyone inside the company has freedom and responsibility. This culture empowers the engineers there to build amazing tools that make employees very happy, but in the meantime the stacks they built may not be suitable for serving individual enterprise customers. For instance, they certainly don't fully use the elaborate security infrastructure that AWS offers. They don't worry too much about being frugal, either. Remember the famous saying that "Netflix is a log company that happens to stream movies"? They do store everything, at the cost of millions of dollars. Their monitoring system is so easy to use and so expressive, that it blows out any known monitoring systems out of water, but in the meantime it requires thousands of machines (amazingly, it used to be only 4 engineers manning the whole stack. A perfect example that shows how much productivity good systems can bring to engineers). So, yeah, great company and great stacks, but it does not mean they can compete in enterprise cloud business.
