For $10k / mo paid 1 year in advance, your cloud provider does a legal review of the situation and figures out how to make your problem work on both the technical and legal level. It's not a "special plan", it's consulting.

Edit: "How do you know?" -- I don't know it's actually what happened, but when switching to enterprise, you don't go from 10% margin to 98% margin. The added costs actually represent added budget for the provider to deal with your "special case". ALL enterprise pricing tiers are disguised consulting contracts.
