I think that lines up nicely with my general point that AWS simply doesn't benefit much from putting resources into this area, although some C-level folks might be enticed by shiny marketing materials about "Best in Class Cost Controls & Monitoring" For other option, it does seem like GCP (I don't know much about Azure in this) is a little better in this area. Admittedly, I'm speaking from limited experience playing around with free tiers in both, along with the stream of stories that we hear about AWS. I think it's also fair to point out that cost controls may not have helped much in the example of this particular article: If your account gets hacked, presumably the hacker will also have some access to remove cost controls.
