Earlier quoted context omitted.
In my opinion, and maybe I'm an absolutist about this, the fact that there aren't these guardrails is opportunistic and predatory. Agile, iterative design and testing will inevitably lead to failures, that's the whole point. Marketing a cloud service to developers who need scalable and changing access to computing during that process should take that into consideration.
I do not think the intentions here are to be opportunistic and predatory but inability to empathize with small developers. A large customer will very likely just pay off few hundred thousand dollars extra expenses. It is only individual developers who are at risk here and cloud operators do not have much interest in them.
To me it looks very similar to the personal checking overdraft schemes banks were using up until a few years ago.
