Why would they? I’ve been running Internet servers (web, DNS, SMTP, IMAP, database) for about 25 years and until recently have only had the roughest idea of what EC2 or an S3 buckets are. It’s only because my employer recently started working with a new company that uses AWS that I’d have heard of SES. Also, I’ve no idea what the Azure equivalents are. If I ever need to know, I’ll find out but until then, ignorance is bliss.
