I empathize with you, but your experience highlights the flaws in the approach you're advocating.

I'll use myself as an example: I'm a self-taught developer who has built and managed high-profile, high-usage websites/web applications. I probably could not pass one of your algorithm-based FizzBuzz tests, but if I was hiring and you suggested that a site should scale simply because you threw it on a large AWS instance, I would not consider your candidacy further regardless of your ability to pass a FizzBuzz test.
