<Insert every cloud provider here>.
There are countless posts on HN that describe people and businesses being blocked by a cloud provider like GCP.
Hetzner is by all means not an outlier.
Signed up with Contabo without incident and have been a happy customer ever since.
Look, whether or not Hetzner chose to block me out of blatant geo-racism is not at issue here, I wouldn't want to do business with them either way since they declined to give me a reasonable explanation and I wouldn't feel secure with a provider like that.
