Your point does stand, though, that not all cloud providers have the bandwidth price gouging. I was mainly referring to GCP/AWS/Azure, who set the trend for the rest of the major providers.
DigitalOcean is a VPS provider, not a cloud provider, and that's pretty similar to pricing on the nearest comparable AWS service (Amazon LightSail), not something showing DO as notably better (1Core/2GBRAM/60GBSSD/3TB transfer @ $10/mo or 2Core/4GBRAM/80GBSSD/4TB transfer @ $20/mo.)
Though if you are optimizing price per TB of transfer quota, LightSail does best with the 1Core/1GB/40GBSSD/2TB transfer @ $5 instance size.
From the first paragraph in https://en.wikipedia.org/wiki/DigitalOcean
> DigitalOcean, Inc. is an American cloud infrastructure provider[2] headquartered in New York City with data centers worldwide.[3] DigitalOcean provides developers cloud services that help to deploy and scale applications that run simultaneously on multiple computers.
You might have your own cute definition of “cloud”, but it doesn’t match the industry so get over it and stop correcting people.
DigitalOcean gives 3TB bandwidth on a $15 2CPU/2GBMEM/60GBSSD instance. If you ran 1350 of them it'd cost you ~$20k/month and get you your 4PB egress within bandwidth allowance.
