That's a whole lot of text for "I had a 14 GiB VM image publicly linked and people discovered it", and none of it has much to do with AWS or Cloudflare.
Presumably the author would do much better with a VM or something from OVH, they'll just shut you off or limit you before it becomes a problem (not that they would care about 30 TiB).
