I totally get the tradeoffs, but that's not what I'm talking about. For example the popular Hey article was 10 years into their operations and they were spending multiple millions with AWS. That's not a startup anymore, and they don't need to optimise for unexpected 10x growth. At some point for new companies it transforms from "good decision" to "total cost is comparable" to "we should notice cloud doesn't make sense now" to "we're years late and failed at planning".
