You need to account IO load as well, more bandwidth means more requests to the disks and I assume they will use mechanical HDDs for the storage, SSDs are still too expensive to support $0.015/GB. Good mechanical drive can give you up to 200 IOPS and maybe 200MB/s, so they will have to copy the data a lot to be able to increase capacity on demand. Making it free doesn't seems to be sustainable at all.
The offer is no doubt competitively prized, but it's no doubt much more lucrative than people using Cloudflare as a CDN for their s3/b2/azure/whatever.
