A lot of people suck up to them, they seem to require formal ID proof to authorize your account outside EU and they can deny you without any reason whatsoever. If you look up online about similar things happening to others, the standard response you would see is "If you don't like them, take your business elsewhere". I would rather pay more with digital ocean than to be treated like untouchable with hetzner.
> ID proof to authorize your account outside EU
They do that even within EU, and even when your credit card passes 3D secure validation.
