You’ve interpreted the numbers wrong. Yes, Linode, DigitalOcean, and most of this class of providers charge $0.01/GB. Almost literally an order of magnitude less than Azure or AWS. The megaclouds massively overcharge for bandwidth. It’s not even close.
AWS charges $0.09/GB, and Azure charges $0.0875/GB.
Maybe Troy Hunt gets a discount for being a Microsoft Regional Director and MVP. (Neither of which make him an employee of Microsoft, confusingly enough.)
Ah weird. I was on some AWS page that said the cost was $0.01/gB, which threw me off as seeking ridiculous compared to what I remembered. Not sure what page it was, but clearly that is not the actual pricing.
