I find it weird that the article focuses completely on demanding AWS to change, instead of just telling people to look for alternatives. In fact the other services mentioned (Azure, GCP, even Oracle) don't even have an unlimited free tier like AWS. The author says it's not the student's responsibility to make sure they don't go over their limits, but according to this pricing model it absolutely is. And if the student is afraid of that responsibility, just find another free tier elsewhere.
