Knowing which company, that your live depends on, know how to make things right is crucial knowledge - thus the popularity of those threads IMO.
When years of your life gets deleted in seconds, and the company starts ignoring you, that's the red flag that needs to be public.
I'm not advocating for separate section, but the public have spoken - the popularity of those threads means it's crucial part of this community.
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.
