Not taking sides here, but I think that the cloud is complicated enough (especially for a person that does not specialize in it), to miss one of the edge cases that can lead to the huge bill.

In a few minutes, I can set simple PHP script with curl, that will launch 100 requests each second, using a pool of hundreds of thousands of IP's thank to the rotating VPN.

This is an edge case of course, but it can happen.

I use cloud myself, but only cloud servers, which allows me to control budget better and provides me with an "escape plan", where I can just switch to dedicated quickly.

There is a difference between "cloud" and serverless though. I bet most people are not using something that can autoscale infinite by default.

Absolutely, just like with software engineering missing the edge cases can drive you out of business.

I am not sure why people think that cloud is magically will shield them from every bad decision.
