I really don't see how they can. The business and usage details of their clients are confidential. We have their word that ToS where violated, I don't really think they should say more. This needs to go to arbitration.
You're already placing blame here.
We don't know the details other than what Railway has said.
If Railway did something wrong, then letting that be known may help other customers avoid the same ~mistake.
Is that possible? Absolutely.
Has Google also done similar things before? Absolutely.
I certainly wouldn't bet my house on either possiblity.
