Yup.
One day, as you spend vast resources tracking and cutting and worrying about your AWS expenses, you’ll think “hey I could cut 100% of AWS costs by not using it!”.
Thinking about cutting AWS costs is your first step on the journey to never using it.
That’s great, until realise that you’re now spending money on infrastructure elsewhere instead.
I’m not going to pretend AWS is cost effective for every type of problem. But the comments here are overly simplistic.
Also, and more generally, I find it disappointing that when someone has made an open source tool to help the community, most of the comments are cheap attacks at the cost of running AWS. Poor etiquette guys.
