I'm not disputing that there are situations where it makes sense to pay a high risk premium. What I'm disputing is that price doesn't matter. I get the impression that companies are losing the capability to make rational pricing decisions.

>Unless on premises helps the bottom line of the main product that the company provides, these decisions don't really matter in my opinion.

Well, exactly. But the degree to which the price of a specific input affects your bottom line depends on your product.

During the dot com era, some VC funded startups (such as Google) made a decision to avoid using Windows servers, Oracle databases and the whole super expensive scale-up architecture that was the risk-free, professional option at the time. If they hadn't taken this risk, they might not have survived.

[Edit] But I think it's not just about cloud vs on-premises. A more important question may be how you're using the cloud. You don't have to lock yourself into a million proprietary APIs and throw petabytes of your data into an egress jail.
