Doesn't AWS force customers of their free tier to provide a valid paying method (i.e., credit card) to be charged once any limit is surpassed?

You can throttle serverless services by invocation count. AWS will alert you when an account exceeds a budget, Azure used to let you put a hard limit on the spend, not sure if they still do.
