Since they are not going to do it anyways, they are no worse off, and the customers get a legally binding guarantee resolving their concerns, and it provides just cause to the good actors in Microsoft management to head off or remove any elements besmirching Microsoft’s reputation.
Sounds like all wins to me and it is what any B2B contract with Microsoft would do (well in the contract rather than publicly) if they wanted that guarantee so it is not even a particularly novel legal request.
