Unfortunately two things in the way of that are will and the cost of building a long tail of product features. First, that I'm not interested in running a standalone business, and second - my research here (it's been a lot) depends on being able to spend 20% effort on an 80% solution. I don't build a dynamo or a SNS and don't need a sales and marketing budget when I'm embedded in a large company building something purpose-built. The overhead of normalizing for industry wide generic use cases kills the 500% dream.

There's obviously room here though because AWS definitely takes a margin and that means opportunity!
