AWS understands lifetime value of the user, not just the account. I've had mistakes ON MY PERSONAL ACCOUNT that were in no way connected to my work. Times when I was just experimenting. They refunded it in full. I've also heard from STUDENTS who may not ever get into infra work that they're still reasonable and lenient.

You would be absolute mad to use any other platform. AWS gets it right on the customer service front. Amazon, perhaps deeply less so... but AWS? amazing.
