That's true but Fly's PaaS is perhaps more comparable to DigitalOcean's App Platform (its PaaS). For that, DO include 100GB for free while Fly include 160GB. Beyond that, DO charge $0.10/GB while Fly charge $0.02-$0.12/GB. Cheaper bandwidth for Fly's Machines (more comparable to droplets, as far as I can see) would be neat though.
