I wasn't trying to make a point other than sharing examples of companies, like Akamai, that store a lot of personal data on behalf of others. Storing data with Apple is storing it with Akamai, and all of the other third parties involved--where "third parties" becomes a blanket term in privacy policies and not an exhaustive list. The "chain of trust" in this regard has some missing links.
So far as their businesses are concerned, the data is safeguarded and I would never expect it to be sold--not by the top of the data food chain in any case.
But there's the issue of data being stored with US companies requiring being subject to US laws, such as the USA PATRIOT Act.
