None of that is commercially viable (so far), and commercial activity really doesn't benefit from this at all. What matters is the 'stuff' you get for your money. AWS knows this (as does Azure and GCP), as do the B2B customers. It's just a simple sum. Either the customer does more of the hard but generic work, or the provider does more of the hard (generic) work. You make two calculations (including potential benefits of vertical integration) and you pick what works best. "Inventing" generic compute with an API, web console and service-wide IAM is possible, but adds no value at all to say, e-commerce. So you might as well just pay some vendor to already do that, and if possible to do it at a scale and quality you will never be able to reach as a single business anyway. So you go to a cloud since that already has it and you can't replicate it anyway. If it turns out to be expensive but still cheaper and better, that's a win, OSS/SSPL be damned.
