It's worse. For a 16 vCPU + 32GB RAM + 20TB traffic (fly.io has max 8 vCPU) I would pay around $750 on fly.io instead of €30 on Hetzner. People are willing to pay a lot for I guess an easy deploy story ?
Through also it's not a fair compression because for the kind of services where being close to the edge and redundant over many places matters Hetzner isn't even an option. AWS maybe, but AWS is also pain in my experience.
