This is a weird take on an incredibly useful paradigm (serverless). One the one side, there are obviously precautions that all of these users could have taken to avoid these charges on the other hand its totally common to spin up a thing and forget about it or not do your due diligence. I totally feel for the people who have been hit with these chargers.

At the end of the day though the whole think feels like a carpenter shooting themselves in the foot with a nail gun then insisting that hammers are the only way to do things.
