While that's true, other quality providers still smash AWS on that issue.
Let's say you spread that across 10 dedicated instances ("optimized droplets") on DigitalOcean, at a cost of $800. They account pool the droplet transfer, so that's 50tb with the instances. The remaining 550tb would cost you $5500.
$6,300 vs $37,300 and you get ten servers with DO.
And if you really wanted to be creative, spin up 100 $20 instances, which would cost you $2,000 and give you 400tb of pooled transfer. Then spin up the 10 $80 optimized droplets to use for actual work (maybe there would also be some use case for the 100 standard droplets with 2vCPUs and 4gb ram; otherwise idle them). That gets you down to $4,300, almost a tenth of what AWS is charging just for the transfer.
When it comes to transfer, AWS is a minimum of 5x more expensive than it should be even if you assume a premium for the service. It's a big fat money maker for them.
