No sooner than I posted that I began to wonder if I mis-heard that number (pretty sure I heard that number on a podcast... which now that I think of it, might have been hyperbole to make the point that Google
really
wants people to check out GCP and, ideally, get hooked). Microsoft had their BizSpark program which granted $150/month in Azure credits plus operating system, server, and enterprise edition developer licenses for three years, a value that comes to far more than $750 a month if you really use to its maximum potential. The best I can find at the moment is $300 but I don't know if this is per month and if it's just limited to K8S research/education or not:
