Earlier quoted context omitted.
You're angry in the wrong direction. It is not their fault that you, or someone in your company, didn't read their TOS. Hetzners service is cheap, this attracts bad actors. In their eyes you are a bad actor and according to their TOS they're right. I, as a customer of Hetzner, are happy about how they deal with people abusing their services.
We read their ToS. Our lawyers read their ToS. It has a vague “we can kick you off if we choose to” part, but removing service with no recourse was not ok. So we told them we would sue them if they didn’t give us access to shred sensitive data and they relented.
If your lawyers thought that this line means something different than "don't use crypto, mining, etc. we will lock you out", you should change/sue your lawyers. This is a clear as it gets, I see zero fault on Hetzners side.
